Orient RA-AC0N02Y10B M-Force ACON Diver's Automatic Orange Dial Watch

Orient RA-AC0N02Y10B Diver's Watch

The Orient RA-AC0N02Y10B is a men's automatic diver's watch with a 45 mm stainless steel case and matching bracelet. Its orange dial features index markers, luminous hands and a date window. Water resistance is rated to 200 metres or 660 feet, and the crystal is sapphire. It suits wearers who want a mechanical tool watch for daily use and recreational diving.

Strap Adjustment and Crown Operation

The stainless steel bracelet is resizable and uses a deployment clasp for a secure fit. A screw-down crown must be unscrewed before setting the time or date, then screwed back down to maintain water resistance. The bidirectional rotating bezel turns in either direction for timing dives or other intervals. Forgetting to tighten the crown after adjustment is the most common cause of water ingress.

Sustained Wear and Automatic Movement

The automatic movement recharges through natural wrist motion and never requires a battery change. During continuous wear the mainspring stays wound, keeping the watch running day and night. If the watch is left unworn for more than a day or two it will stop and need a manual wind and reset. The 12.8 mm case thickness sits comfortably under cuffs for extended periods.
