My favourite watch is the Seiko SKX007:
Usually on a B22 rubber strap like this:
Imo it's the best designed mechanical divers watch at any price -
- The mechanism has an effective 20 year service interval and is one of the best designed mechanicals at any price - see eg
http://www.thepurists.com/watch/features/8ohms/7s26/- The lume is outstanding
- It's ergnomically faultless - notice how the crown is placed low so that it less likely to stick in your wrist and the "venting" (those bends) in rubber strap so that it adjusts to fit your wrist better; the underside of the case is beveled too and there are no sharp edges
- You can buy spare hands, faces, gaskets, whole mechanisms at reasonable prices and they are easy to fit; it's one of the last mechanical watches designed as a tool instead of a status symbol
- It's notoriously tough - not as tough as a G-Shock but almost certainly tougher than almost any other mechanical watch; again, it's designed as a tool, so the glass is toughened borosillicate - not as scratch proof as sapphire, but a lot more impact resistant, the case is oversize to allow more shock absorb - even the springbars are a special oversize design
- Good production engineering and tool-not-prestige marketing mean that the price is insanely low for an ISO certified mechanical divers watch - say around $250 on the net, which is a lot less than the
service on a Rolex
Downside: they come unadjusted from the factory with only 20 sec a day accuracy guaranteed. Most seem to "regulate" to chronometer accuracy (a good jeweller can do this for you while you wait) but then you'll have to start servicing more often.
