The San Martin watch has incredible quality. The sand like style is very eye catching and very pleasing to look at. The movement is flawless and every feature has been made with great detail. Taking links out to get it to fit my wrist was super easy with the mini tools that came with the watch. To get a watch with this much quality and mechanics is incredible, I’m already looking to buy another.

Great watch! Looks even more gorgeous than in the pics. My only nitpick would be the sharp edges of the bracelet and the clasp, but you can easily fix this with some sandpaper.

Bad:
Takes smudges easily.
gmt dial is misaligned defeating the purpose of this watch's special event.
on the fly is a bit finicky but can live with it.
not sure about it I like it dislike the Polishing in the middle of the bracelet.

Good:
the dial is so beautiful with it's original design.
the case finishing is top freaking notch.
amazing on the fly adjust on bracelet.
male endlinks make it a very macho looking watch.
solid endlinks and solid clasp

It is a solid watch that is elegant and sporty at the same time.

The quality of the surface treatment is good, there are no comments on the bracelet, the play in the links is small, the clasp is solid. The watch itself is small and relatively lightweight. I don't like those. There is no feeling of things on the hand. Dial without phosphor. The watch is packed in a compact round zipper case, convenient. How, in my opinion, the watch is overvalued its price up to 25 K. I cannot say how accurate the move is yet. Mechanism quiet back cover deaf. Against the background of the same lightning, fame, look simpler. But is quite consistent with the East. This is what I can compare from my collection.

Great watch, for $250 USD on sale I'm confident there's almost no watch under $700 that truly beats this San Martin outright! Mine literally runs at +-3 SPD! I assume they do some regulating of the movements because that is beyond incredible even if this watch sold for 5x the price. I counted mine at 44-46hrs power reserve.

The dial is beautiful, the setting of the watch feels very tactile/confident, and the bracelet is more comfortable than even $800 swiss watch ones!

Literally my only issue has been a stiff micro adjustment with the clasp, but it seems to be loosening up over time. This has quickly become a daily wear for me and one of my favorites.

Received in about a week from China to Australia. The quality of the watch is very good, better than the two Seiko I’ve owned. One or two design decisions I’m not very fond of but other than those it’s a really good watch. I particularly like the dial. My wrist is 7.5 inch, about 18.5cm, it looks a little bit too small on my wrist for my liking, 40mm would be perfect.

Arrived in 7 days! My first San Martin and I now see what the hype is about. For the money this is incredible value. The dial is beautiful at reflecting the light and the case and bracelet finishing is very high quality. A standard NH movement and you can tell it's a budget movement when setting the time and changing date/GMT hand but that doesn't bother me as I rarely do it. All in all very happy with my purchase and it won't be my last San Martin. Can't understand what took me so long.

let me say San Martin watches are the best value for quality available. With that said my free return option was nothing more than a headache of no contact(5 days with nothing form SM) or very lazy info(clear cache, try new network) when the printing label can't or couldn't be downloaded or printed! The watch was just a tad to small and i was interested in sending this one back for the 42mm GMT with MOP dial but SM customer service drug their decision making process out until i gave up and will just keep the watch. I WON'T BUY FROM THEM AGAIN HOWEVER. Nice product but eh customer service = less than satisfied customer
