Cal. SW280-1 M is a hand-winding movement with moon phase and date from Sellita. Like other Sellita SW200 movements, it is based on the design of the ETA 2800 family, though ETA does not sell a direct competitor with the same functions. Sellita has produced this movement since 2018. Cal. SW280-1 is an automatic version of this movement.

The moon phase indicator is a disc located at 6:00 on the dial and the date window is located at 3:00.
