Orient RA-AC0E01B10B Automatic Watch

This Orient automatic watch features a 40mm stainless steel case and matching bracelet with a black dial. It is suited for adults seeking a classic dress watch powered by mechanical movement rather than a battery. The silver-tone hands and index markers provide clear analogue time reading. A date window adds daily utility without cluttering the face.

40-hour power reserve and 100m water resistance

The automatic movement stores up to 40 hours of energy when fully wound, so the watch keeps running through a weekend off the wrist. Water resistance to 100 metres or 330 feet covers swimming and surface water sports but not diving. The fixed bezel and mineral crystal protect the dial from everyday knocks and scratches. Buyers needing ISO-rated dive specifications or longer power reserve should consider other models.

Stainless steel bracelet with deployment clasp

The solid stainless steel bracelet uses a deployment clasp that secures with a single push, reducing wear on the links compared with a traditional pin buckle. The case back is transparent, revealing the movement, while the crown is a standard pull-push type for setting time and date. The bracelet is resizable and adjustable for a precise fit. Those preferring leather, rubber or NATO straps will need to purchase alternatives separately.

Questions about this item

Will the 40 mm case and 12 mm thickness sit alongside my older dress watches without looking oversized?

The case measures 40 mm wide and 12 mm thick, a classic dress proportion that pairs well with similarly sized vintage pieces.

How can I confirm the automatic movement is running correctly after I set it?

Watch the silver tone hands and index markers advance smoothly, check that the date changes at midnight, and observe the rotor through the see through case back.

What comes in the box and what must I purchase separately?

The watch arrives in its original box with booklet, fitted on a stainless steel bracelet with deployment clasp. No extra items are required for immediate wear.
