Questions

Frequently asked questions

  • Does Smartlet work with all Rolex Daytona references?
    Smartlet covers Daytona references across 19mm / 20mm lug widths via the standard spring-bar system. Check the Daytona model guide for the full reference table, including vintage and current generations.
  • Will the Apple Watch sensors work on the inner wrist?
    Yes. The inner wrist position maintains constant skin contact, so heart rate, ECG, SpO2, and wrist temperature all operate normally, along with notifications and Apple Pay.
  • Does Smartlet affect the Daytona's chronograph?
    No. Smartlet attaches at the lug ends via spring bars. The case, pushers, and movement are untouched, and the installation is fully reversible in seconds.
  • Smartletは機械式時計にダメージを与えたり、改造したりしますか?
    いいえ。Smartletは既存のバネ棒システムを使用して、標準的な時計ベルトを交換します。時計ケース、ラグ、またはダイアルに永続的な改変を加えません。このプロセスは数秒で完全に可逆的です。機械式時計は影響を受けず、元のベルトを再度取り付けることでいつでも独立して着用できます。Smartletは時計職人の精度で設計され、それが組み合わせられる時計と同じ注意深さでテストされています。
