8 reviews for SAN MARTIN mechanical diving watch 100 meters waterproof explorer SN020-G with YN55A movement

  1. David C. (verified owner)

    I’ve always like the look of this vintage style dial, but the smaller size was just a bit too small for my taste. This San Martin SN020-G is a dream come true. 39mm case that is slim and contoured beautifully. Nice finish! The vintage lume applied to the dial give just enough vintage vibe, but not too much. The crystal looks better in hand than the pics can show. Over all a nice clean look that stands out but yet flies under the radar.

    It would be wrong of me not to comment on the bracelet. It may be my favorite bracelet! Great finish. Female end links make for a great fit and look coming off of the lugs when wearing. And the clasp looks and operates beautifully. I couldn’t ask for anything better.

    I recommend this watch for those looking for a nice watch of this style with a vintage vibe.

  2. Bob Sacamano

    This is a very well made and nice looking watch overall. The finishing on the case and bracelet are fantastic. But why are there three different San Martin logos on one watch? No premium brand mismatches like that. Either have the logos match or leave them off. Having an unsigned crown and bracelet would be better than having logos that do not match.

  3. Luciano (verified owner)

    The watch with custom dial is above all my expectations. The quality of finish, the general look, the precision of the movement, how the customization has been performed… all these details fit together perfectly in a very beautiful ensemble. The movement came adjusted to + 2 / +3 sec/day, I really can’t be happier than this. I have been surprised by the professionalism of the interface, the quick responses and the perfect understanding of my needs behind them. I am really grateful to San Martin for creating this little gem for me. They just earned a loyal customer. Thank you.

    Great watch with excellent finish. Currently running well at only15 seconds a day slow. Buying price says $258US which is equal too Approx 187.43 GBP. I had a huge argument with my bank as I thought they where at fault for a poor exchange rate but the Bank gave me at top exchange rate of $1.39 to £1GBP. But the merchant charge me £214.72GBP which is actually $299.69US. not the $258 advertised that is a huge $42.69US more than the advertised price!!!! The bank has investigated this and confirmed that the my rate given to me by them was $1.39US to £1GBP. And that the the extra $42.69US was charged at the merchants (SAN MARTIN) end of the sale. Not good.

      Hello Mr.PAUL CLARKE,

      Thanks again for your support!

      I see your left a comment on our store about your SN020-G order, sorry to see the price difference, it must be international transaction fee.

      But the prices you mentioned are not correct, as SN020-G is $258.00, you select FedEx delivery, that’s a $28.00 delivery cost, so in total it’s $286.00 as it’s shown on the page, the total price you paid is $299.69, so that’s a $13.69 difference, I just applied a $14.00 refund, it will take some time before both of our banks can process it, but you will receive it safely, thanks!

      Warm regards,
      Glenn Yu

    Dear MR GLENN WU, many, many thanks for your swift reply and the part refund of the transaction/currency fees. Much appreciated. As a customer buying dozens of watches each month for my collection from different online outlets all over the world I was surprised by the extra cost but I am genuinely delighted at SAN MARTIN’s speedy rectification of this and will buy again in confidence from SAN MATIN WACHES and equally recommend you for the fabulous products you make, speedy delivery service and excellent customer service you provide. My grateful thanks to all at SAN MARTIN WATCHES for a wonderful, high quality product.

    I’ve collected watches for many years. I’ve owned a Rolex Submariner, Breitling Navitimer, Zodiac Sea Wolf, etc. This watch looks just as good as any of them. I just love it. San Martin hit a home run with this watch.

  7. Kurt Nunn

    Great watch. Would love to see dial color and lume variations for this size model. It is my “go to” watch.

  8. Kazuya Shibata (verified owner)

    Fast shipping and excellent packaging was excellent.
    Although it was a slightly older model, I felt that the quality was worth more than the price. I think it’s fair to expect even higher quality from the latest models.
