Longines L960 Movement Technical Reference | L960.001, L960.2 & Battery

The Longines L960 is an extra-thin vintage quartz calibre associated with early-1980s Longines ladies’ watches. The connected Gilded Hour catalogue contains L960, L960.001 and L960.2 records, so this page treats them as a documented catalogue family while keeping replacement claims watch-specific.

Battery and replacement guidance

The battery data is not uniform across the live Gilded Hour records. L960, L960.001 and L960.2 examples include 364 / SR621SW entries, while other L960 records show SR516SW. Do not select a replacement battery from the family name alone: inspect the movement marking, battery well, insulator and cover, and check for leakage or corrosion.

No ETA base movement or universal replacement interchange is asserted here. A nominally similar cell can still be wrong for the clamp, height, polarity or available clearance in a particular case.

Service notes

The L960 is a thin vintage quartz movement. Service should be limited to a suitably equipped watchmaker who can protect the circuit, coil, battery contact and fragile case construction. Record the original battery orientation and photograph the movement before disassembly.
