A: Yes. A 20ATM (200-metre) water resistance rating, combined with a screw-down crown and diver-grade construction, makes this watch genuinely suitable for recreational scuba diving, snorkelling, and swimming. Always ensure the crown is fully screwed down before water exposure.

Q: What is the NH35A movement and why does it matter?

A: The Miyota NH35A is a well-regarded 24-jewel automatic self-winding movement known for reliability, accuracy, and ease of long-term servicing. It winds automatically from the natural motion of your wrist, requiring no battery replacements.

Q: What strap options come with this Tandorio dive watch?

A: The watch comes fitted with a 20mm leather strap with a bracelet clasp. The 20mm lug width is a standard size, making it easy to swap in aftermarket straps — rubber, NATO, or metal — to suit your style or activity.
