Wear a smartwatch with your Seiko SKX Diver

In short Smartlet One fits the Seiko SKX: the original SKX007 and SKX009 and the 2024 reissues SRPL83K1 to SRPL89K1, on 22mm lugs. The SKX uses fat spring bars, but its 1.1 mm lug holes take the watch adapters in their place. No modification to the watch, fully reversible.

The SKX007 is the most modded watch in the world. Discontinued in 2019, it remains the benchmark entry-level diver: reliable 7S26 movement, 200m water resistance, and an aftermarket ecosystem larger than most luxury brands.

The problem
Choosing between health data and horological heritage every morning.
The solution
On the SKX (SKX007, SKX009 and the SRPL83 to SRPL89 reissues), Smartlet One replaces the strap: the watch adapters seat in the lug holes in place of the spring bars, and your smartwatch sits on the same wrist. Both watches run at the same time, with no modification to the watch, and the change is fully reversible.
