A aluminium case is what the Sector R3251171001 is built around, in a generously sized case. It measures 40 mm across.
Case and Wrist Presence
Case diameter is 40 mm, worked in aluminium. At 40 mm it lands in the range most men’s wrists take comfortably, and it will sit under a cuff.
Movement and Functions
A quartz movement drives the watch. That means accuracy which needs no daily attention, no winding routine, and no rate drift to correct.
- Multifunction – several indications on one dial
- Water resistance – 3 ATM (30 metres)
- Mineral crystal – protecting the dial
Water Resistance and Everyday Durability
The watch is rated to 3 ATM, or 30 metres of static pressure. That covers rain and incidental splashes. Take it off before you shower or swim. Make sure the crown is fully seated before any contact with water.
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.
Care and Maintenance
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. Keep it away from the shower and the pool – the rating here covers splashes, not immersion.
Keep it clear of perfume and solvents, off the speaker on your desk, and out of direct sun when you take it off.
About the Brand and Ownership
The appeal of a Sector 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.
The Short Version
What you are getting is an everyday size that still has presence. 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.
