£99
Not a toy. Not suitable for children under 14. Contains small parts — keep away from young children. Treat it as not water resistant. A watch is only sealed if its gasket, case back and crown are fitted correctly, and on a self-assembled watch that’s down to your build — so we don’t give these a water rating. Keep it dry.
Tools sold separately — see the complete tool kit. First time building? Read the FAQ or see our build guides.
The ST1655 is an automatic mechanical chronograph calibre — a true mechanical stopwatch complication, not a quartz imitation. Sold as a movement + case + dial combination. Paired here with the rose gold-tone chronograph case and complete calendar moonphase dial.
