40 mm quartz watch with leather strap

The Oceanaut OC7210 is a 40 mm analogue watch powered by a quartz movement. Its stainless-steel case pairs with a white leather strap secured by a buckle. The white dial has no date window or chronograph function.

Style-focused wearers seeking a simple daily watch

Buyers who want a clean, fashion-oriented timepiece with a white dial and leather band will find this model fits the brief. Those needing a date display, stopwatch function or higher water resistance for swimming should look at something else.

3 ATM water resistance rating

The case is rated to 3 ATM, which equals 30 metres or 100 feet of static water resistance. This level protects against splashes and brief immersion but is not suitable for swimming or diving.

Questions about this item

How much noise, heat or power draw should I expect from the quartz movement when the OC7210 runs all day?

The quartz movement is silent, produces no noticeable heat and draws negligible power from its battery during continuous daily wear.

What strap tool or accessory do I need to fit the 18 mm leather band on the OC7210?

The leather strap uses a standard 18 mm spring-bar fitting and a buckle clasp, so a basic spring-bar tool is all that is required for adjustment or replacement.

Will the 40 mm stainless-steel case and 3 ATM water resistance of the OC7210 hold up alongside my older mechanical watches?

The 40 mm case matches many vintage dimensions, while 3 ATM resistance covers splashes and rain but not swimming, so treat it as a daily-wear companion rather than a dive-rated piece.
