Josh, Client Executive in Mississippi, describes his experience with Smartlet

Josh is a client executive based in Mississippi. He travels internationally for work. He has owned his Rolex Submariner for 22 years and has no intention of leaving it behind when he travels. He also wears an Apple Watch Ultra for the data, the alerts, and the connectivity that his professional life demands.
For years, those two facts sat in tension on his wrist. Smartlet resolved it.

A Rolex Submariner held for 22 years is not just a watch. It is a record of a career, a companion on every trip, a constant in a life full of variables. The idea of replacing it, even temporarily, with a smartwatch is not a trade-off most collectors are willing to make.
Josh was not willing to make it either. What he needed was not a replacement but a solution that respected both devices equally.
"I've worn this Submariner for 22 years. It is not staying home because I need my Apple Watch."
The Submariner's 20mm lug width falls natively within Smartlet's supported range of 18mm to 24mm, requiring no modification to the case. The full compatibility guide is available here: https://smartlet.io/pages/compatibility-brands
Maxim, a General Manager in Prague, made the same decision with his Rolex Sky-Dweller: the watch was not going into a safe, and the smartwatch data was not negotiable. You can read his story here: https://smartlet.io/blogs/stories/maxim-rolex-sky-dweller-smartlet-review-prague

The Apple Watch Ultra is a substantial device. Its titanium case, its size, and its sensor array make it one of the most capable smartwatches on the market. It is also the kind of device that earns its place on a wrist when the wearer travels across time zones, manages back-to-back meetings, and needs reliable connectivity throughout.
Smartlet positions the Apple Watch Ultra against the wrist with full skin contact maintained at all times. ECG, crash detection, temperature sensing, heart rate, and all other sensors remain fully operational. No functionality is lost.
For users concerned about ergonomics during long travel days, the bracelet dimensions are comparable to a standard steel bracelet: 60 to 100g in weight, 9 to 12mm in height on the wrist. The Smartlet One Classic (https://smartlet.io/products/smartlet-one-classic) handles continuous daily wear without discomfort, as confirmed by multiple users working at laptops and traveling with the setup in place.

Traveling with a valuable watch has always required a certain level of awareness. With Smartlet, the analog watch sits on top, visible and protected, while the smartwatch sits underneath against the wrist. The combination draws attention for the right reasons.
Josh reports that colleagues and clients notice the setup and ask about it consistently. The reaction is curious rather than confused. A French company solved a problem that no one in the watch industry had formally addressed, and the result sits visibly on the wrist.
As covered in our article on how to wear a smartwatch with a luxury watch safely (https://smartlet.io/blogs/magazine/wear-smartwatch-luxury-watch-without-scratching), the engineering of Smartlet is designed to protect both devices during exactly this kind of active daily use. Steve, a retired engineer in California, reports the same finding after months of continuous wear alongside his Rolex and Monaco: https://smartlet.io/blogs/stories/steve-retired-engineer-in-california-wears-his-favorite-timepieces-and-monitors-his-heart-thanks-to-smartlet
