Description

The Reflex Active Nexus 100 S Lite is a unisex smartwatch with a 39mm square aluminium case, a digital display with a customisable watch face, and a silicone strap, reference RA-NX-100S-L-07.

Case & crystal

The square case measures 39mm and is made of aluminium, a light material that keeps the watch comfortable through a full day of wear. The strap is silicone, so case and band are different materials: a rigid aluminium case paired with a flexible strap. The Nexus collection gives the case a compact, geometric case profile.

Dial

Instead of a printed chapter ring or applied indices, the dial is a digital display. Its customisable watch face lets you change how time and data are laid out, so the same 39mm case can read as a simple time-only screen or as a more data-led layout.

Movement

This is a smartwatch rather than a mechanical or quartz-analogue watch, so there is no beat rate, power reserve or hacking seconds to speak of. Two tracking functions are built in: a heart rate monitor and a step counter, both viewable on the digital display.

Bracelet & fit

The silicone strap is the only band option on this reference, and it is supplied as the watch's sole strap. Silicone is flexible and soft against the skin, which suits a watch intended for continuous wear alongside heart rate and step tracking. It is covered by the manufacturer's warranty: 1-year Reflex Active warranty.

On the wrist

At 39mm square, the Nexus 100 S Lite has moderate wrist presence and is sized for both smaller and larger wrists, in line with its unisex design. The aluminium case and silicone strap point to everyday and active use rather than formal dress, and the step counter and heart rate function suit anyone tracking daily movement.
