Interesting comment Sross, why dont you like the idea of a mechanical movement?
Hi FoxFish,
Mechanical movements don't have the kind of accuracy I need. The best certified chronometer mechanical movements are accurate to +/- 2 sec per day, approximately, and even some of the high end, multi-thousand dollar Swiss brand names gain or lose 5-6 seconds per day. I'm often out in the field where I have no access to a time signal, or internet time servers, and I often need a watch that is set to within seconds of UTC. I can't afford to have a watch that is out by more than a minute within less than 2 weeks, sometimes sooner in the case of mechanical dive watches that get exposed to wide temperature swings.
By comparison, I've measured the accuracy of my Traser tritium watch, and it gains less than 3 seconds per month, even when it is used for diving.
The other issue with mechanical watches is their power reserve. If you only have 1 watch that you wear all the time, it's not an issue, but I have a collection of watches that I use for different purposes, and some of them don't get used that often. An auto watch winds itself down in 2 or 3 days, and if you go away on a trip for a couple of weeks it'll be dead when you get back, and you'll have to reset it as well as wind it. My quartzes are always happily running when I go away & come back. Some of the hardcore automatic watch enthusiasts actually get watch cases with little reciprocating display mounts that keep the watch from running down, but I'd rather just keep it simple & get a quartz.
Auto watch enthusiasts like the fact that they don't need batteries, but high-end auto movements need to be opened up and serviced every few years if the watch is going to last and stay accurate- just like quartz watches need to be opened up for a new battery (and service) every few years, so I'm not seeing any advantage there. Also, Citizen and Seiko have removed the battery replacement issue with quartz movements by using photocells or mechanical generators to keep rechargeable batteries topped up, but I'm wondering whether accuracy will suffer, at least for analogue watches, if people don't bother opening them up for service?
An interesting piece of trivia: the most accurate watch in the world, the Chronomaster, is made by Citizen and is only marketed directly by them in Japan. it is accurate to better than +/- 5 seconds per year. They make various styles using the movement, including some very beautiful jewelry models in solid gold, platinum & titanium. The finish of some of these models rivals the best Swiss units, and the Chronomaster is a major status symbol among watch geeks in Japan.
Of course, now with atomic clock time radio broadcasts, any cheap quartz watch can set itself to within microseconds every day, as long as it's getting reception, but that doesn't work in India yet, so I'll stick with my trusty Traser for now
Incidentally I have just bought a new watch! I was just searching the web looking for watches relating to the thread & came across this 40 year old Omega & just couldn't resist....
That Seamaster is a beauty! Does the strap really have purple tones in it, or was the colour introduced by the camera?
