Our view

Decent, without standing out

35 of the 140 quartz watches within 20% of its price are better equipped (crystal, water resistance, titanium). You choose it for its design or its brand, not for its spec sheet.

Depending on what you want

If you plan to swim with it, take the Longines HydroConquest instead: water-resistant to 300 m, at €1,550.
If you prefer a case with more presence, the Longines HydroConquest measures 42 mm, at €1,550.
If you would rather have an automatic movement at the same price, the Mido Ocean Star 200C Titanium has one, at €1,350.
If you want to spend less without losing anything on the spec sheet, the Alpina Alpiner Extreme Quartz AL-220BG2AE6B costs €1,195.
