Wear a smartwatch with your Porsche Design Chronograph 1

In short Smartlet is compatible with the Porsche Design Chronograph 1. Lug width: 20mm / 22mm - natively supported with no adapter. Installation uses the standard spring-bar system. No modification to the watch required. Fully reversible in seconds.

Ferdinand Alexander Porsche designed the original Chronograph 1 in 1972 - the same year he completed the 911 Carrera RS. Black titanium case, black dial, black subdials. Every surface treated to eliminate reflection. The concept was legibility through reduction. The Chronograph 1 became the first all-black watch in production history and defined a design language that still looks current fifty years later. The contemporary references continue that logic in aerospace titanium.

Questions

Frequently asked questions

  • Does Smartlet work with the Porsche Design Chronograph 1?
    Yes. The Chronograph 1 uses 20mm or 22mm lugs depending on case size - both natively supported by Smartlet. No adapter required.
  • Which Porsche Design Chronograph 1 references are compatible?
    All references - 40mm at 20mm and 42mm at 22mm, including titanium, PVD, and COSC-certified variants. The full catalogue is within Smartlet's native range.
  • Will Smartlet affect the all-black finish of the Chronograph 1?
    No. Smartlet attaches via the spring-bar slots only. The titanium case and PVD finish are not touched. The Shadow finish in PVD black is particularly well-matched to the Chronograph 1 aesthetic.
  • Where can I buy Smartlet for the Porsche Design Chronograph 1?
    Smartlet is available at smartlet.io in Classic, Shadow, and Titanium. The Shadow finish is a natural match for the Chronograph 1's all-black identity.
  • 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。
