Men's watch Riedenschild 46 mm silicone strap black dial

The first thing you notice on this Riedenschild is how it is put together: a screw-down crown locks into a round 46 mm stainless steel case in a silver tone, with a sapphire crystal over the black dial. It is a diver's watch for men, powered by a Miyota 1S13 quartz movement.

Built for the water

The watch is rated to 100 ATM, and the details back that up. Always screw the crown fully home before you get wet, and rinse the watch in fresh water after a swim in the sea. Have the seals checked from time to time. There is also a helium valve, a feature made for professional divers working in saturation chambers, which adds to the genuine diving-watch character. The sapphire crystal resists scratches well, and its anti-reflective treatment keeps the dial readable in bright sun.

Reading the dial

Black dials are quick to read, even on the move. The hands and hour markers are luminescent, so once they have been charged by light you can still read them in the dark. A window shows the date. The rotating bezel works as a simple timer: line its marker up with the minute hand when you start, and the elapsed time can be read straight off the bezel.

Size and movement

At 46 mm across and 13 mm thick, this is a large, solidly built case that suits broader wrists. The quartz movement keeps accurate time without any servicing. When the battery eventually runs down, have it replaced by a watchmaker, who can check the seals at the same time.

The strap

The black silicone strap is 22 mm wide and made for active use, since a rinse under the tap is all it needs. Quick-release fittings let you take it off in one movement, no tools required. If you like the idea of a sporty strap, you can browse more men's silicone strap watches.

It is an easy watch to live with, from the office through to the weekend, and it comes in a presentation box, so it works well as a gift too.
