Riedenschild men's watch blue dial 46 mm 100 ATM diver

The case of this Riedenschild diver is stainless steel in blue, with a screw-down crown and a helium escape valve built into a 46 mm round body that is 13 mm thick. It is a men's watch with a blue dial, a quartz movement and a black silicone strap.

Case, crown and water resistance

At 46 mm, this is a large watch, so it suits wider wrists. If you are unsure about fit, the watch size guide explains how to measure your wrist against case diameter. The crown screws down onto the case, so make sure it is fully tightened after every adjustment and before you go near water. The helium valve is a feature taken from professional saturation diving equipment. Water resistance is rated at 100 ATM. After a swim in the sea, rinse the watch in fresh water, and have the seals checked from time to time.

Dial, bezel and strap

The blue dial is easy to read at a glance. The hands and hour markers are luminescent, so after exposure to light they stay visible in the dark. A window shows the date. The rotating bezel lets you track elapsed time: line its marker up with the minute hand at the start, then read the time passed directly from the bezel. Inside is a quartz movement with analogue display. When the battery runs low, take it to a watchmaker, who can also check the seals. The black silicone strap rinses clean under a tap. Another practical detail is the quick-release fittings, which let you remove the strap without tools.

For everyday wear, the diver styling stays fairly restrained, so the watch works on the beach, at a desk, on a run or in the workshop.
