The latest Prospex offerings (which I agree are too large) follow on from a range of now obsolete (and mostly JDM only) AGS and then Kinetic GMT movements, all with the same true GMT hacking feature.
Some of them were truly dive rated (e.g Scubamaster model SBCW003), others (e.g. Flightmaster SBCW005) were only 100m.
There are now Sportura Kinetic GMTs, like the SUN015P1 also available now, but these are also 100m and lack any movable bezel, as far as I can tell.
Some of the Landmasters also used the same movement, but personally, there is little I hate more than a pointless compass bezel. They revolt me.
I always wanted to try out the flightmaster, I like the look of the dual texture bezel. I believe there are a couple available for sale now.
In general (and I have looked hard at these, I too thought it would be a perfect holiday watch), the whole range is beset with lack of bezel, silly bezel, can't change the strap, too large, too ugly and all sorts of problems. The Flightmaster seemed the best of the lot, though the Scubamaster also looked good. SCWF has a
Scubamaster for sale now, and I just joined to ask about it, but I need to wait before I can PM, so if you're a member, why not try him.
