Questions

Frequently asked questions

  • Is Smartlet compatible with the JLC Reverso?
    Yes. The Reverso Classic uses 18mm lugs and the Reverso Tribute uses 20mm - both natively supported. The swivelling mechanism is completely unaffected.
  • Does Smartlet interfere with the Reverso swivelling case?
    No. Smartlet attaches at the fixed lug spring bars. The swivelling caseback operates independently and is not involved in the strap attachment.
  • Which Reverso references work with Smartlet?
    All of them - Classic, Tribute, Duoface, Grande, One. Lug widths range from 18mm to 22mm, all within Smartlet's native range.
  • Does Smartlet work with the Jaeger-LeCoultre Reverso?
    Yes. The Reverso Classic uses 18mm to 22mm lugs, all natively supported by Smartlet. No adapter required.
  • 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。
