DIETRICH OT-series Swiss automatic

The OT-series Swiss automatic is an in-house movement from Dietrich, introduced in 2022 and currently in production. It features a 24-hour disc with small seconds and a day/night indicator, offering a distinctive time display layout uncommon in mainstream calibers. As part of the Dietrich OT family, this movement represents the brand's push toward proprietary mechanisms. It powers contemporary OT-series watches in the brand's collection.
