Think fresh cocktails, dazzling light and endless roads, top down in a convertible, with the Dual Time Lime on your wrist. Summer is officially on.

A radical aesthetic, between shadow and light

The 24-hour counter at 9 o’clock and the retrograde date at 1:30 create a strong horological identity and enhance readability.

SPEAKE-MARIN “IN-HOUSE” MOVEMENTS STRATEGY
 
 Since 2015, Speake-Marin has initiated a movement strategy to fully develop and assemble proprietary movements within its atelier in the Neuchatel area, Switzerland. This new strategy gave birth to the “SMA” collection, which includes Openworked, closed dials and Haute Horlogerie movements. Firstly, Speake-Marin focused its efforts on Haute Horlogerie 3 Hz movements (Minute Repeater and Double Tourbillon). Then, Speake-Marin developed Hour Minutes Seconds 4Hz movements, which were featured in the new One&Two design as an Openworked movement named SMA01. This movement is particular due to the small seconds counter being positioned at 1:30 and its integrated micro-rotor. The new SMA02 Calibre is part of the SMA movement family and follows the Openworked collection approach with the small seconds at 1:30. The small seconds at 1:30 meets the Speake-Marin objective to break-away from the watchmaking codes: Speake-Marin is the only watchmaker who positions the small seconds there. It is actually a real constraint in terms of movement development since the small seconds at 1:30 have to go through the time setting module.
