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.
