Corum Round Ref. 89102 Silk Dial 21 Jewels Cal. 2824 Automatic OH Serviced 1970s

This is a Corum round-case dress watch.

Corum was established in 1955 in La Chaux-de-Fonds, the sacred home of watchmaking.
It is a luxury watch brand that continues to create innovative and unique masterpieces unlike any other brand.

Corum's brand icon, the key emblem, symbolizes 'innovation' that opens new doors,
and is placed on the dial, case back, and crown.

This model features a stainless steel case and a snap-back case back.
The crown is original Corum, with the key emblem.

The dial features a delicate silk pattern and a polished finish, creating beautiful shadows depending on the angle of light.

While many vintage Corum watches are manual-winding, this one is a rare automatic.

This watch is recommended for those looking for an antique watch with a chic design.

How to Operate

The movement equipped is automatic.
It has no second hand, but features manual winding, date display, and quick date set functions.
 

How to pull out the crown: Gently pull it out by inserting a fingernail between the case and the crown from the back.

To move from the 1st click to the 2nd click, operate it like a lever.
Pulling the crown too hard may cause it to detach. Please pull it out gently.
To prevent the crown from bending, please remove the watch from your wrist before operating.
Gentle operation can reduce stress on the crown.

Manual winding: Turn upwards with the crown in the normal position.

Time setting: Pull the crown out to the 2nd click and turn downwards.

Operating the quick date set when the watch is indicating "9 PM to 2 AM the next day" will cause damage.
It is recommended to set the time to around 6 AM before performing the quick date set.
