Orient Watch Company was founded in 1950 in Tokyo. The brand quickly gained recognition for its dedication to mechanical watchmaking and developing its own automatic movements. Vintage Orient watches are prized by collectors for their distinctive designs, in-house movements, and impressive value.

This piece features a stainless steel case and strap. It will fit wrists of up to 21 cm. Please check the detailed pictures. Water resistance has not been tested, therefore it must be treated as NON-waterproof.
The watch will be delivered in a new padded box as seen in the photos, for a better protection during transportation and for a smart and safe storing once you receive it.

Date quickset by pulling the crown to the second position and turning it to advance the date. As with any other vintage mechanical watch, exact accuracy cannot be guaranteed, as it depends on many factors, including your kind of use. It has been regulated in different positions to minimize the average time gain/loss. The watch has been serviced in July 2025.
