    to summarize my impressions: awesome watch, just buy one already! Actually buy 2, because I’m sure that Tiffany Blue is amazing in real life, too.

    I bought this model as a personal memento, custom logo and text and it has easily became my favorite yet! A timeless design in a 37mm beautifully finished case with vintage appearance, but all the modern specs we should appreciate: high beat accurate movement, sapphire crystal, applied indices, BGW9 lume, solid end links. The whole package screams quality way above the price point. The movement of choice (PT5000) works accurately and the action feels smooth, both with winding and screwing. Above and beyond all the esthetical features, this watch sits very comfortable on the wrist thanks to the case design and dimensions and being well balanced with the bracelet. Well done, San Martin, hat off!

    Phenomenal watch. I recommend the 36 (37mm) over the 39mm, the dial looks more balanced. The build quality is top notch and I am extremely satisfied. you might compare this to a Smiths PRS Everest. I haven’t held that particular watch but I can say it is a lot easier to get this San Martin than the Smiths. The applied indices add great depth to the dial and the matte black color can look almost grey at times with how it plays with the light. This helps the watch stay legible in bright sunlight. The case size is just beautiful. At first when I first opened the box I thought it looked a little small but once you put it on the wrist it just looks so right. This watch punches well above it’s weight and easily fills that SARB033 role. SW200 movement, Explorer look, precision execution all for less than $500 USD, amazing watch
