What watch you're wearing?

I'm giving this Tissot PR50 another try. Nice simple watch and very light due to the titanium. Nice and slim as well, 7mm thick. The tiny Channelocks work great to pull pins out when adjusting the bracelet. My F91w, daughter's apple watch, and my grandfathers old Bulova that my mom gave me are in the background. I also have a vintage Seiko hand wind en route from Japan. Oops.
Tissot is another old brand still kicking. The PR50 looks like a great value.
 
Still have not sprung for the cost of service for that, still functioning, vintage Tudor.
Oh! That's not good. Mechanical/Automatic watches are funny like that.... and definitely not in a good way. They can function perfectly well. Even keep excellent time. Meanwhile on the inside the gears are bone dry and one day very soon will completely seize up due to grinding against each other with no lubrication! Not slow down in terms of time-keeping accuracy to indicate there's a problem. No. I mean completely, seemingly out of no where just grind the gears to destruction. Have seen it happen sooo many times to other watch collectors/enthusiasts. Usually to the point where a service is not going to cut it anymore. We're talking complete overhaul of the watch's innards. And, sometimes; on a vintage watch.... good luck with finding replacement parts.

How are such watches able to continue to keep excellent time? No clue! None! All I know is it's a phenomenon that happens, and it's extremely common.

Uh.... no Dave
 
Stopped by a Walmart while I was out this evening. Perusing the selection of Casios and this guy was sitting there. I've had this model a few times and sold them off in package deals. Something about it works for me though so giving it another go. It scratches the analog itch without much cash. I've heard someone describe it as the analog equivalent of the F91w. Works for me.

1964 Seiko Sportmatic dolphin snap on case back.
It was the only year that version was produced. In '65 they went to all versions having a screw on back. It was built to be able to handle snorkeling. They also did a "seahorse" version in '64 only. It was the only screw back case for the Sportmatic in '64. It was the only year for a Sportmatic seahorse at all. Before the water30proof (30m) and seahorse (50m rated) they were designed to be water tight to 10 meters.

The ED on right of the case reference and the 4 pointed star indicate the afforabable version of whatever model it is. AD was mid grade and SD were the best ones.

By '65 the infamous 6xMAS dive watch was produced. The cases were no longer water tight via pressurized by pushing on the snap back case but had begun using the screw on type. Before the screw back, the mere act of pushing on the snap back via a snap back vice caused some internal positive air pressure to build up, thereby helping keep water out. It truely was water tight to about 30 meters down.

The 6xMAS (in 65 the 62MAS) was expensive so not many were sold. A few hundred according to rumors but Seiko never said. The next version did sell better but still nothing like Seiko's other watches. These days those are highly prized where entry level watches like the Sportmatic can be found in good condition for $200 or less.

Edit: I changed some of the post for acuracy. At first I said stated the dolphin back was 64 only for the Sportmatic. The snap back case dolphin was 64 only but dolphin back's were made after '64, only with screw on case backs.

Got a question for everyone:

I'm looking for an alternative to the mechanical watch I now wear to the office and dress occasions. I need something rugged for when I work in the yard, go hiking, camping, etc.

I do like the Casio Tough Solar Atomic series. Aside from the lunar phase and tide indicator, any other differences between the 6900-1 and 7900-1? Are the displays different in crispness/shadowing?

I'd like to add I have an $85 Amazon gift card burning a hole in my digital pocket.

The solar models don't have great screen visibility angles. Many people don't care. I found it annoying to the point that I just stuck with the F91w. It's not solar, but the battery can last for 10 years plus, and it's not atomic, but it's very accurate as is.

My son has an F91w. Solid watch at a great price. Just seems too small for my wrist…
