What watch you're wearing?

Just FYI, COSC doesn't test a fully assembled watch like METAS does. Cosc tests the assembled movement, and assumes the chassis will allow it to operate unimpeded.

If you demand utmost stringency in timekeeping, METAS would be the way to go.

On a semi unrelated note, I have a cheapo pagani "homage" to an Omega seamaster that uses the budget nh35 movement, and has +8/-2 spd under practical observation over the course of a month of actual use. It's a diamond in the rough, and the movement adjustment still allows for more tweaking either way.

As some of the others stated earlier, it all depends on your usage. For me, in terms of practicality, precision, and if I could afford it, I'd either get a Citizen with their 0100 Calibre or a Grand Seiko with that fancy scmancy spring drive.
I am not looking for the ultimate level of accuracy. For me, the certification is like an insurance policy against inaccuracy, inconsistency and unreliability. I would prefer METAS certification but even COSC is sufficient for my peace of mind. On the other hand, I am aware that insurance policies are not free of charge but nothing is.
 
If the watch is serviced, parts replaced, movement adjusted, etc they generally bring the watch back into compliance with original specs, but do not send off for recertification.

If they can bring the watch back into those specs, why certify to begin with?

METAS has a bit of an edge here with certifying parts for antimagnetic quality, so as long as it is all OEM nothing should change there, but it isn't like Omega send the watch back to Geneva after warranty work and recertifies.

Like much of what comes out of Switzerland, it boils down to marketing more than anything.
When buying a new watch, I cannot be certain that it is within the specs that are declared by the manufacturer, no matter what these specs are. If it is certified, however, I am certain that it is within the specs that are declared by the certification institute. In other words, the certification eliminates the uncertainty factor. I prefer eliminating this factor before paying for the watch, especially if this is a luxury watch.

How can you be certain the certification company is any more trustworthy than IWC or Breitling, though?
At a certain point, you have to trust somebody, right?

Or.. I mean, it's a watch. Just wear and compare to NIST time, which is free. After twenty four hours, do the math. Or after a week and take an average. Then you know.
If it is outside spec, open a warranty claim.
 
I wonder if I am missing something about the certification going out the window after the very first time the watch gets serviced. First of all, if the watch is serviced properly by an authorized service center, wouldn't it be as accurate and as robust as it initially was? If this is a certified watch, what will go out the window?
The guarantee that the watch is accurate within a specific set of seconds in terms of gaining or losing time. That goes out the window. The reason why the guarantee ends is because many customers get cold feet about spending several hundreds of dollars servicing their (for example) COSC certified watches, properly. (Within a certain set number of years each time.) Due to that, the various brands make it clear that the original certification is no longer valid.

They have no clue if perhaps the last time the watch needed servicing, the owner didn't have it done at all. Or, perhaps had it done by some ham-fisted moron who bought a cheap set of the more common watch-makers tools off of eBay, and had at it! Claiming to be an independent watch-maker who has years of experience. Perhaps the watch was sold, after several years. The new owner wants servicing done properly. Well, the service center obviously won't guarantee the now old certification after someone who had no business poking around inside the movement screwed the caseback down after they were done. You can get a new certification from the brand's own service center. That's going to cost more. But they won't honor the original COSC certification once they open up the watch. Plus, if your watch is quite old, service center might not even offer a new certification.

Truth is, most watch owners don't bother. They realize that a truly experienced independent watch-maker can regulate their favorite watches to run more accurately after just one visit.
Secondly, am I wrong in assuming that under normal conditions the watch would not need servicing at least during the warranty period (and probably a good bit later if it is not worn extensively)?
On average, a typical watch needs servicing once every 7 years. Usually once every 5 years if it's an older vintage model. With some newer models, an individual brand might say 10 years. Whether you wear a watch or not, it's best to stick to those intervals. At least that's been my experience. I'm sure others will disagree. Mechanical/Automatic watches have a very odd tendency of being able to keep accurate time.... While the oils on the inside get gunked up or thin out far too much. You look at your watch, you think everything is fine. But on the inside, you have gears grinding against each other without proper lubrication until the watch completely stops dead! Winding it, shaking it; nothing!

Now you need to get the watch completely overhauled (hopefully there are spare parts available to replace the destroyed old ones. Not always the case with older, in-house movements). A regular servicing isn't going to be enough.
 
I have a chronograph (Seiko Prospex) and I agree that its less legible than others. I still wear it though because I think its beautiful and its really comfortable to wear. Your Dekla's really nice.
I understand that. To be honest, while I do wear watches for their time keeping function, the watch I chose to wear from one day to another essentially comes down to which ever one grabs my fancy as I visually scan the collection. Their looks matter a lot to me, in addition to keeping good time. So in that sense, they also serve me as fashion baubles. I greatly enjoy looking at them from time to time on my wrist when I have no interest whatsoever in knowing just what time it is.

Being retired and quite a home-body, I wear a watch of some sort every day, 24/7. Not because I need to know the time for any important reason, but simply for the joy of seeing an attractive watch on my wrist. No one else sees what watch I am wearing (even my wife doesn't notice.) I just wear a watch for my own enjoyment. Simple pleasures for a simply mind.

I have also found that after a couple of years fussing over the accuracy of my watches, I don't pay any attention anymore to how few seconds a given watch is keeping in accuracy. It doesn't really even matter if it's 2 seconds a day or 15 spd. In part because I only wear a given watch for two or three days in a row anyway, before switching out to a different watch.

I guess if I only wore one watch, all the time, I might be more fussed if the watch didn't stay within a few spd. But most automatic watches these days tend to do well in that regard, or can easily be regulated to do so. And quartz/solar quartz watches are stellar for time keeping.

Thus, I think that whatever watch one chooses to buy and to wear is just a personal right and no justification to anyone else is needed for any reason. Life is short... enjoy beauty, design, and visual appeal as much as you can, while you can.

(Sometimes, of my thirty or so watches, I do wear one of my chronographs, simply to enjoy that complicated, sporty look! Readability be damned. 😂)

I greatly enjoy having a wide variety of watches to choose from to wear - to suit particular moods, attire, occasions, activities, or frivolous whims!

You are right in pointing out that I cannot be absolutely certain about anything. I also comprehend that feelings like insecurity and skepticism do not improve life quality, especially if they go to extremes. My point is that I wouldn't like IWC or Breitling to be the jury. The independence or the honesty of any third party jury is also questionable, indeed, but questioning who the jury is, in the first place, makes more sense for me. Certification would give me peace of mind in hoping that I wouldn't have to open a warranty claim but I agree that buying a watch without this hope would not be the end of the world. I am not ruling out IWC based on certification but Breitling gets an edge due to COSC certification.

And thus... the reason I buy watches that if ever need be, I can replace the movement myself, or have it replaced for the same money as, or less than, a modestly priced service fee. I do like to tinker and have regulated a number of my watches using a TimeGrapher. Quite fun to dial in a movement oneself, to within a couple of seconds a day. 😎 If I had a very expensive luxury watch, I would not want to tweak it myself. And I'd be frustrated if it wasn't running to my satisfaction. I just don't need that in my life.

I also greatly enjoy my quartz watches (and solar quartz watches)... and they do keep exceptionally good time - I never worry about my watches, especially my quartz and solar quartz watches!

For me, getting a watch (or car, or else) properly serviced is part of the joy of ownership. Since it needs servicing, it also deserves it because it gives me something in return. Otherwise, I wouldn't buy it in the first place. This is interaction between watch (or car, or else) and owner. If it deserves expensive service, this is the outcome of my initial choice (of buying it). Neglecting or skimping on servicing would make me feel like not getting my dog to regular vet visits or like skimping on dog food. This would disturb my joy of ownership. The more unnecessary the item is (luxury watch or luxury car as opposed to more affordable ones) the more uneasy I would feel if I would fail in giving it what it deserves.

I wouldn't let any unauthorized person, ham-fisted or artisan; fiddle with my watches, anyway.

I'm with you here. I regulate anything in the box that's outside "house specs" of +5 seconds in two positions. One of the little things about the hobby that keeps it from being just raw consumerism.

Then there's the ETA C07.611I have had no reason to fiddle with it whatsoever, and have been more than happy with its performance. But it was "laser regulated" at the factory and you have to adjust the balance wheel weights. That has kept me from purchasing anything else with that movement in it. I'm just not kitted out to work on those, and have no reason to invest in the ability just to be able to work on Powermatics.

Learning to do some tweaking on a watch is like learning to do some gun smithing or knife sharpening, or flashlight emitter modding, fountain pen nib tweaking, or modifying one's guitars' electronics or pickups... this level of involvement greatly deepens one's engagement with the item/hobby and enriches the experience. It also helps continue one's skills and abilities. Plus, it's just damn FUN to do all these things. 😀
 
On the wrist for the last couple of days... though the dial be a little busy, the readability is quick and clear to read quite accurately. These swords are my favorite set of watch hands.

The watch runs about 7 seconds fast per day - perfectly fine time keeping by me.
 
Just purchased a chrono with the Sea-Gull ST1901 auto movement. These are all over Amazon and I got the 40mm version however they also make a 38mm and 42mm. This is the best deal going right now for an automatic chronograph and at under 200 dollars it is a fairly decent watch. Sea-Gull is no longer providing this movement to many sources and as such it will be hard to find anything once the current stuff is sold out. Fun little watch and every watch type person should have at least one hand wind mechanical chrono in their collection...

Seiko "Dress KX" I modified a little. Saphire crystal and coin edge bezel, one of my favorites to wear.View attachment 75529
Great looking watch and quite easily readable. There is a lot to like about that watch, the crown placement at 4 o'clock and how deep-set it is, the hands, and the coin edge bezel is very cool.

Nice example of a cleanly done chrono that maintains easy readability.
 
Ha, good question...picture is misleading, it is not that tight.....I hate a tight watch band.
If possible, could we see just how thin it is? i really like thin lol. If Citizen could just make a bn0200 diver at 38-40mm with a 9-10mm thickness, I'd be all over that in a heartbeat. And chamfer off some of the hard angles in the bracelet too...i get that it's a tool and should look as such, but the angles get quite uncomfortable for extended wear. I have 7.25" wrists, but they swell and deflate depending on what I'm doing or eating at the moment.
