My Mechanical Watch

A manual-wind mechanical watch is powered by a mainspring wound using the crown. Wind it according to the instructions for its reference. Stop if you meet firm resistance; never force the mechanism.

Setting your watch

Crown positions, setting directions and date-adjustment restrictions vary by reference and movement. Follow the instructions for your particular watch rather than a general sequence. If you are unsure, ask Tempvs before adjusting it.

Do not force the crown or a calendar control. If a screw-down crown is fitted, secure it correctly after use without forcing or cross-threading it.

Water resistance

A model’s original depth rating is not confirmation of the current water resistance of a pre-owned example. Vintage watches should be kept away from water unless their current suitability has been specifically confirmed. Ask us about the individual watch and its pressure-test status.

Service and running performance

Service intervals and power reserve vary by model, age and use. Follow the manufacturer’s guidance and seek an assessment if the watch develops a fault or a significant change in performance.
