Our review
The GW-M5610-1BER is the square G-Shock in an all-black finish, with Tough Solar charging and radio time sync. It is a 43 mm digital with a 200 m rating that is built to take knocks and mostly looks after itself. The all-black look is discreet by G-Shock standards. The catches are the chunky case and a resin build that will not feel premium.
What it is
The GW-M5610 is the solar, radio-controlled version of the classic 5600 square case, and the 1B reference is the black-on-black treatment with a resin strap. It sits in the middle of the square G-Shock range, more capable than the basic battery DW-5600 and simpler than the steel and Bluetooth versions.
The all-black finish with a dark display and minimal colour gives it a stealthy look that suits people who find the standard G-Shock too loud.
The movement
It is a quartz digital watch with Tough Solar charging, where the face collects light and charges a rechargeable cell, and Casio says a full charge runs it for months in the dark. Multi-band radio sync sets the time from transmitters including the UK signal, normally overnight, so the time is very accurate with no input from you. Alarms, stopwatch, countdown timer and world time are all on board.
The rechargeable cell lasts many years but is not infinite, so a service eventually applies, although there is no routine battery change.
On the wrist
The case is about 43 mm across and tall, so it sits prominently on the wrist, though it is light because it is resin. The strap is soft rubber-type resin with a standard buckle, comfortable for all-day wear. The buttons are rubberised and easy to use. It is a casual watch and does not suit smart clothes. Anyone with a slim wrist should check the case height and width on the listing.
Water and everyday wear
It carries a 200 m rating, allowing swimming, snorkelling and showers. The crystal is mineral, protected by a raised bezel. The shock-resistant construction is the main selling point. An LED backlight lights the display in the dark, and there is no lume on the digital display. After long exposure to sunlight, black resin can fade slightly, but that is cosmetic.
Against the alternatives
The Casio G-Shock GW-M5610U-1ER is the near-identical sibling with a slightly different finish. The Casio G-Shock GW-BX5600-1A1ER is a connected version of the same shape. The Casio G-Shock GW-5000U-1ER is the premium Japanese-built option. The Casio G-Shock DW-5600E-1V is the basic battery alternative.
Who it's for, and who should skip it
It is for anyone wanting a watch that sets itself, charges itself and takes knocks, in a discreet colour. Skip it if you want a mechanical watch, a slim or smart look, or if you are not near a radio signal and want the self-setting to work often.

Who shouldn't buy this
Don't buy it if you want a mechanical watch to look at and look after: this runs on light and a quartz movement.
