I have been lurking a while and trying to educate myself about mechanical automatic watches. I hope some experts can help, I am thinking of buying my first mechanical (automatic) watch and I am a bit confused about the movements (and other things!). Many watches claim to use the same movement (e.g., the ETA 2824-2 25 jewel movement seems very common). Are these actually the same in the various watches or am I missing something?
For example the following are my top watch candidates (to date) both clain to have ETA 2824-2 movements, sapphire crystals, super-luminova hands, etc. Would one with the ostensibly the same movement be expected to keep better time, be more reliable, etc? I guess what I am asking is: do manufactures "tune" the common movements to achieve better preformance?
Two I like:
Hamilton Jazzmaster viewmaster (~$545 on line at Right Time International)
Stowa Airman automatic date (~ $680 + shipping direct from Stowa)
What I am looking for is something like these watches - simple, not too expensive, easy to read, not too big (40-41mm dia, < 12 mm thickness), with date, non-scratching crystal, and good luminous hands/numbers. Suggestions for other bands of these type (pilot?) watches in this price range?
