Silicone, nylon or metal: which replacement strap

The strap is the accessory that gets replaced the most. Silicone or fluoroelastomer withstands sweat, chlorine, and seawater, can be rinsed under the tap, and is suitable for both swimming and trail running. The braided nylon strap with Velcro adjusts to the millimetre and breathes during long outings. Titanium or steel outfits the watch for the week, but can slide and mark the wrist during exercise. The key point remains the lug width, in millimetres, often twenty, twenty-two, or twenty-six, as well as the fastening system: classic spring bar, quick release, or manufacturer-specific attachment.

Cable, dock and replacement charger

Each manufacturer uses a unique charging connector: clip-on, magnetic dock, induction puck, or pin cable. A second cable, kept at the office or in a suitcase, prevents being stuck with a flat watch while on the go, and a longer model makes it easier to charge on a nightstand. Compatibility with the exact model number should be verified, as the same manufacturer may change connectors between models. Before charging, rinse and dry the contacts: sweat and salt can corrode them and cause intermittent charging. The watches themselves are grouped on the smartwatches page.

Film, glass or bumper: protect the screen

The film made of polyurethane fits curved screens and absorbs minor scratches from daily use without altering the look of the watch. The tempered glass offers better protection against impacts from rocks, pull-up bars, or climbing holds, at the expense of a little thickness. The bumper, a case that surrounds the bezel, protects the edges, the most exposed area during a fall. For swimming, choose a protection that adheres perfectly, as any water getting under the film can affect the touchscreen. Even with a sapphire glass watch, which is more durable, protection is useful for climbing, technical trail running, or cross-training.

Handlebar mount, heart rate strap and sensors

The handlebar mount turns the watch into a bike computer: you take it off your wrist, secure it on the handlebars, and read speed, power, or navigation without taking your eyes off the road. The chest heart rate strap measures the electrical activity of the heart, reacting faster than the optical wrist sensor during intervals, sprints, or in winter when the cold reduces blood circulation to the wrist. The stride sensors, clipped onto the shoe, refine pace and cadence on a treadmill or in the gym, where GPS cannot receive a signal. These sensors should be stored separately after the session, protected from moisture, and their battery is easy to replace.

Good deals

Great deals can also be found in the good deals, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped within 24 hours are prepared and dispatched within 24 hours. The key events of the year occur in a stable order: Black Friday at the end of autumn, the year-end holidays, the winter sales, the French Days in spring, followed by the summer sales and back-to-school.

Frequently asked questions

Will accessories from one watch brand fit another?

Classic spring bar straps of the same width are interchangeable between brands. However, chargers, mounts, and proprietary attachments are specific: always check compatibility with the exact model before ordering.

How to clean the watch strap after exercising?

Rinse the silicone with lukewarm soapy water after each session, then dry it. Nylon can be hand washed and air dried; remove the watch regularly to clean the skin on your wrist, which sweat can irritate.

Is a heart rate strap compatible with all watches?

It must use the same wireless protocol as the watch, Bluetooth or ANT+, and most models support both. However, some advanced stride measurements are reserved for straps of the same brand.

Can you charge your watch with a phone charger?

Yes, the cable plugs into most USB adapters, as the watch requires little power. It’s best to use a quality adapter and avoid charging the watch while it is still damp with sweat or water.

Which strap to choose for a thin or thick wrist?

Silicone straps often come in two lengths, chosen based on the wrist measurement taken with a tape measure. The adjustable Velcro nylon strap fits almost all wrists and can be tightened over a sleeve in winter.
