Questions

Frequently asked questions

  • Which Speedmaster references work with Smartlet?
    References across 18mm / 19mm / 20mm / 21mm / 22mm lug widths are covered via the standard spring-bar system; the Speedmaster model guide lists every reference, vintage included.
  • Can I still operate the chronograph pushers?
    Fully. Smartlet replaces only the strap; case, pushers, and crown remain completely clear.
  • How does the Fitbit Air hold its sensor contact?
    The dedicated adapter positions the Air flat against the inner wrist, the placement its optical sensors are designed for.
  • ¿Smartlet daña o modifica mi reloj mecánico?
    No. Smartlet reemplaza tu correa de reloj estándar utilizando el sistema de pasador de resorte existente. No realiza ninguna modificación permanente en la caja, asas o esfera del reloj. El proceso es completamente reversible en segundos. Tu reloj mecánico no se ve afectado y puede usarse de forma independiente en cualquier momento reinstalando su correa original. Smartlet está diseñado con tolerancias de relojero y probado con el mismo cuidado que se dedica a los relojes con los que se empareja.
