update on Triton 2000s and Le Mans
We now have our new shipment of Triton 2000s in and ready to ship! We enjoyed a successful sale on the Triton 2000 Swiss Dive watch over the summer. Actually, it was popular enough, that while it was supposed to end mid September, we will go ahead and take it to the end of the month, September 30th is the last day Also, I want to let you all know there is some work being done with the Le Mans series, so expect some exciting things to come your way in the not too distant future regarding that. I will get any specifics on what it will look like and images ASAP. Alright, well there is a two minute update for every one.SamDebaufre Swiss Watches

Questions on quartz? Ask here!
Since I know very little about quartz watches, an anonymous member has volunteered to help us put together a F.A.Q. post to add to the Horology 101 series. This week's installment will be some of the inventions and discoveries that made quartz movements possible, but in a few weeks the answers to your questions will become part of the H-101 sticky. So fire away and we'll try to compile all the responses into one post!Hey, I'm going to learn some interesting things too. I'll start with this:How does a quartz mechanism generate enough power to drive the hands of an analog watch with such limited battery voltage?

Emergency "toughness"?

As such I guess it was designed to be tough enough to survive a crash which it's owner could survive but my worry is that I would use it primarily for mountaineering and, as such, would subject it to much more constant, sustained abuse.Do you think it could take the constant knocks? I mean that both in respect of it functioning as a watch and as a transmitter.I know the vast majority of these things are bought by people who would never conceivably need the transmitter but it is the ONLY reason I'm considering one. I know I could buy a better stand-alone transmitter and carry it with me (and that may be the option I end up going for) but I

winding backwards
Hi - i read on another forum that you should not wind your watch backwards to set the time. I did this on both my Black Bays when British Summertime ended. They don't even have a date wheel - so is this a problem??ThanksGlenn
