Seeing in the Dark: Luminescence in Watches
Wrist watches are naturally quite useful for their intended functions, as we watch-nerds know, especially when you can see them. When it comes to low (or no) light conditions, however, they can get tricky to read. The problem of legibility goes back as far as the history of the wristwatch itself and as technology has evolved, so has the legibility of our watches. A variety of materials and chemicals have been used over the years to bring luminescence, or lume, to wrist watches, with the first solutions coming in the early 1900’s.The early practice of applying lume to wrist watches, around the time of World War I, involved mixing the radioactive material radium with zinc sulfide. Radium had been known since it’s discovery in the late 1800’s and alone in proper doses it has some luminescent properties glowing blue. However the glow of radium alone was not bright enough and the amount required to make it useful would emit too much harmful radiation.if the dial says ̶

Compared to the flurry of watchbuying activity last year, this year has been relatively calm. I've focused on picking up just a few that I really wanted. This one completes my collection of the 'easy to find' Elgin Durabalance models. Beyond this, there's the BW Raymonds that usually go for $200, and the military 804 and 805 models that I've seen go for as much ad $565. This is a 750, 23J Durabalance model, in a case and dial I've not seen before.This one is another 'collection completer' - the last of the goldfilled Horizon Look models that I know of. Again, the next step is much more expensive - the solid gold ones. This was called the 'Continental', and I was lucky enough to get it with a 730, 23J Durabalance movement (it also came with the 718 pre-db). Needs a new crystal, and I happen to have one...Also, just for fun, I picked up a Lady Elgin - it's the lady's model of the Horizon Look, and a match for the 'Celestial' I've posted before.Then there's this one. This is the B

Anybody have a contact....
.for Blancpain? I sent them an e-mail to the general mailbox a few weeks ago that wasn't replied to, and I'd like some information on the Villeret.

Hey guys - I have looked at a couple of these and can't really feel comfortable buying on since I know nothing about the mechanics of the watch. The number of moving parts in a watch like this, combined with the vintage factor makes me a little nervous. Can anyone tell me about the reliability, maintenance, any other costs one should be aware of with this watch... or just any general advice.Thanks,Dan.ebay/itm/Audemars-Pig...item19df4ae8a7
