1. What should I do if there is water in the watch?

If there is only a small amount of water vapor inside the watch, the water vapor will disappear automatically over time, or the watch will be properly heated (recommended ambient temperature is 60 degrees Celsius). After two hours, the water vapor will disappear automatically. If there are some water droplets in the watch, please do the repair as soon as possible.

2. Special instructions:

The fully automatic mechanical watch relies on the movement of the arm to automatically wind the string, so it must be worn for more than eight hours a day to ensure the accuracy of the timing. Some mechanical watches can also be energized by manual winding by rotating the ring 15 times clockwise without pulling the button out. Manual and automatic mechanical watches are not automatic chains, and manual chains are not used to compensate for energy.

3. Warning:

Under normal circumstances, the watch will be able to adjust the date during the period from 8:00 am to 4:00 am, and frequently adjusting the calendar during this period will cause the calendar to be damaged.

Mechanical watches should be kept away from TV, computers and other magnetic fields, so as not to affect the normal operation of the watch.

    All in all, a great homage. Fit and finish are excellent. Gobs of “C3” lume, although the greenish hue in normal light is a tad bit distracting. Watch runs a bit slow at 10-12 seconds per day which is well within specs. NH36 is, however, very easy to regulate. Affordable to replace as well. An automatic Tuna is a huge plus.

    Ordered with a bracelet and rubber strap. The folks at San Martin also supplied an extra NATO strap, spring bars, spring bar tool AND a tool for bracelet pins. Very nice and THANK YOU San Martin. Customer service is above expectations.

    Shipping was fast and trouble free. Ordered 8/26. DHL Express arrived here on 9/2.

    Wish I could include a picture with review. I ordered a generic Crafter Blue rubber strap for this watch. Really ups the game and makes this watch look very “sexy”.

    I was really surprised at how great this watch feels. I had been all over the internet looking up reviews and trying to decide if this was the right Tuna to pick up. It is. Quality is top notch, the value here is absolutely off the charts. It feels super solid. I ordered during a holiday of their side of the world but once they were back in office the watch got here really fast. Just not enough good things to say about this watch. Thanks so much for an exceptional product at a great price! 😀

    Short and sweet after having many Seiko Tuna’s through the yrs both autos and Spring Drives it’s quite fair to say this is my favorite, not because the bezel actually lines up, but for the VALUE San Martin is delivering to the customer.

    Bulletproof caliber, domed sapphire, great execution and water resistance, if you are a Tuna fan this one is great to own.
