Meccaniche Veneziane MV135

The MV135 is an automatic movement produced by Meccaniche Veneziane. Based on the ETA 2824-2 but incorporating Seiko 6R15 technical design modifications, it operates at 21,600 vph (3 Hz) with 21 jewels and features hacking seconds. The hybrid Swiss-Japanese engineering approach, combining an ETA base with Seiko-derived modifications, defines this in-house caliber. It powers the Nereide diver and remains in production.
