I don't know much about Orient but can give you some info on Sapphire Glass / Titanium Watches..........
For work (I need an indestructible watch just like you) my Watch tends to get knocked around and I prefer to wear a Titanium watch with a Sapphire crystal. The last work watch I had was a Ti/Sapphire Revue Thommen, it was light in weight and the sapphire never scratched even with the many bumps/knocks etc. The titanium did scratch just like stainless steel watches but looked good as the scratches were very fine and seemed to blend in with titanium if that makes sense ? Since you are after an indestructible Watch make sure the watch you buy doesn't have an anti-reflection coating on the outside of the Sapphire glass as this coating will scratch in time and look really bad in certain light. You can get a sapphire glass with no coating or a coating on the inside of the glass only. Enjoy the search for your next indestructible watch :thumbsup:
You also have a Titan! not much talk about that Flashlight anymore. Funny you mentioned it as I was thinking about selling one or two of my lights and looking at my collection I always say to myself I will NEVER EVER sell the Titan, to me its priceless
