Sellita
Sellita's day-date automatic caliber, the equivalent of the ETA 2834-2. Adds day and date complications to the proven SW200-1 base architecture while maintaining the same 28,800 vph beat rate and 38-hour power reserve. The additional 0.45mm of height over the SW200-1 accommodates the day display mechanism. A reliable workhorse for brands needing a day-date Swiss automatic at competitive pricing.

The community take
Owners talk.
The Sinn 240 St GZ is praised for its highly legible, contrasting dial and bead-blasted stainless steel case, which benefits from Sinn's hardening treatment. Owners note the crystal is perfect, and the Tegimented PVD bracelet is in near-new condition. However, reviewers flag the inner rotating bezel as slightly wobbly and rattly, and the Sellita SW220-1 movement is described as coarse with rough winding. On balance, owners and reviewers appreciate the Sinn 240 St GZ for its excellent dial legibility and robust case finishing.
