Great watch from San Martin. Very happy with the purchase!
Very satisfied with the watch. The movement YN55a runs accurate (-5sec/d) and even better than the seiko movements I owned previously. The finish is on a high level and I can't say anything negative about this watch. Highly recommend. Personaly I hope that San Martin is doing a Royal Oak hommage in the future.
