i'm afraid that you should count me in the group that hasn't been impressed by the their "original" designs.   They demonstrate San Martin's mastery of metal finishing for sure, but to show off those surface finishes there is just too much metal in the resulting watch.   Their latest limited addition SN0010 shows this:

A lovely piece of finishing, true, but as a practical watch?   And they even take over the top in divers (a genre no stranger to too much case material) with the SN025:

Look, i'm willing to grant practically anything is a matter of taste . . . except, well, that.   

Finally there is the SN026:

The problem with this design is that, for a dress watch, it is a 178g behemoth -- fully 20g heavier than my Submariner homage -- with little grace.  We males wear a dress watch for jewelery in the office; it should not call attention to itself silently speak elegance.  Sadly, although beautifully constructed this design simply doesn't do it.

I love San Martin's and have a dress watch on my wrist while i type these words (during the workday, shhh!).   I has exactly the grace and lovely style that the SN025 lacks . . . but it is the SN059 . . . which is a DateJust homage.   I would happily wear a San Martin to work, but it has to be better than the DateJust.

I have too: it is an Oris Sixty-Five homage (approximately; i don't think Oris made a dial like this) which i had customized as you can see.    It truly is a great, practical, watch:

• While self-evidently a bronze case, it is not the ghastly heavy, over-wrought cases of so many bronze designs (save the Fleigers).   
• The lovely sapphire crystal makes me smile every time i look at it; again, very distinctive while being tasteful.
• The dial -- and i did not expect this when i ordered it -- is shockingly at-a-glance legible; better i think than any of my other watches.  
• On top of all that, and partly due to its modest weight and leather strap, it is much more comfortable to wear than i find other divers.

So i find San Martin SN042-g a fantastic selection; it is on my winder now for casual wear.    It splits that duty with a Cronos Subby, which is only used for heavy outdoors work.

PS My PT5000 loses about 6 s/d and i may get it regulated this spring.
