HISTORY & LORE
First introduced in 1976, the Orient Multi-Year Calendar line is one of the most recognizable designs from Orient Watch Co. By matching the year with the month via the upper pusher, the dial displays a full monthly calendar view at a glance. Combined with a 100m water-resistant tool case specification, this remains a standout collector's choice.
RECOMMENDATIONS
All Antique and vintage watches are mechanical. Repairs require precision, so please handle this historical artifact with care.
- Vintage mechanical watches should not be beaten or dropped - shocks can damage the balance staff.
- Vintage watches are generally NOT waterproof. Protect your timekeeper from direct contact with water, heavy rain, or high humidity.
- If your watch becomes wet it should be dried off quickly. Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust.
- Winding any mechanical watch tight may break the mainspring. Stop winding as soon as you feel the natural resistance tightening up.
- When adjusting the hands of your watch, move them in a clockwise direction only to prevent stress on the gear train.
- Every 2-3 years it is recommended to service, clean, and oil vintage watches to keep them running accurately for decades to come.
- Keep your watch away from strong magnetic fields (large speakers, modern computers, magnets) since magnetic exposure can alter the balance spring performance.
- Vintage mechanical watches naturally experience a daily deviation error of up to a few minutes. An accuracy of +/- 3 to 5 minutes a day is considered excellent for a classic timepiece.
