A stainless steel case is what the Diesel F20610_3 is built around, in a mid-sized case. It measures 38 mm across. Case and Wrist Presence \n Case diameter is 38 mm, worked in stainless steel. The surface treatment is polished. At 38 mm this is a mid-sized case that reads as unisex, and it wears easily on most wrists. \n Movement and Functions \n A quartz movement drives the watch. That means accuracy which needs no daily attention, no winding routine, and no rate drift to correct. \n \n Chronograph – stopwatch timing from the dial \n Water resistance – 10 ATM (100 metres) \n Mineral crystal – protecting the dial \n \n Strap, Clasp and Fit \n The strap is silicone. Silicone shrugs off sweat and water, which makes it the sensible choice if the watch is going to the gym or the beach. \n Water Resistance and Everyday Durability \n The watch is rated to 10 ATM, or 100 metres of static pressure. In practical terms that covers rain, hand washing, showering and recreational swimming. It is not a dive watch, so leave it behind for scuba diving and keep it away from high-pressure water jets. Make sure the crown is fully seated before any contact with water. \n A mineral crystal protects the dial – harder than acrylic and more shatter-resistant than sapphire, which is a sensible trade-off on a case this size. \n Who This Watch Suits \n \n Anyone who wants a mid-sized case that works across genders and occasions \n Anyone who will actually use a stopwatch – or simply wants the busier dial that comes with one \n Daily wear that includes rain, washing up and the occasional swim \n Gift buyers looking for something recognisable, boxed and properly warranted \n \n Care and Maintenance \n A watch at this level rewards very little maintenance, but the little it asks for makes the difference between one that still looks sharp in five years and one that does not. Have the battery replaced by a watchmaker rather than a kiosk – a proper service reseats the case gasket at the same time, which is what actually preserves the water rating. A flat battery left in the case is the single most common cause of avoidable movement damage. Rinse the case in fresh water after a swim, especially in the sea, and dry it before it goes back on. \n Silicone cleans up with warm soapy water and a soft brush, which is worth doing occasionally to stop the underside picking up a shine. Keep it clear of perfume and solvents, off the speaker on your desk, and out of direct sun when you take it off. \n About the Brand and Ownership \n The appeal of a Diesel is that it is unmistakable. You are buying a design point of view rather than an anonymous case with a dial in it. Quartz keeps the running costs near zero – a battery every few years and the occasional seal check is the whole of the maintenance schedule. Basic care goes a long way – keep it clear of solvents and perfume, rinse the strap if it has been in salt water, and store it somewhere dry. \n The Short Version \n What you are getting is a case that wears close and stays out of the way, a chronograph dial with enough going on to hold your eye. It is not trying to be a heirloom piece and it does not price itself like one. It is a well-made, recognisable watch that does the job every day and looks considered doing it. \n Technical Specifications \n \n Attribute Specification \n Brand Diesel \n Model / Reference F20610_3 \n Gender Unisex (38 mm case) \n EAN 8430622789069 \n Case Diameter 38 mm \n Case Material Stainless steel \n Case Finish Polished \n Crystal Mineral \n Movement Quartz \n Strap / Bracelet Silicone \n Water Resistance 10 ATM / 100 metres \n Country of Origin ES \n \n Buying With Confidence \n Buying a watch online comes down to trusting the seller, so here is exactly what you get.
