Student Electronic Watch

The Allentian 9109 is a lightweight digital wristwatch built for everyday timing needs. Its plastic case and strap weigh just 31.2 grams and fasten with a stainless-steel pin buckle. The electronic movement drives a 38.8 mm dial protected by an acrylic mirror and a thick 304 stainless-steel case back. A button crown controls all functions.

Swimmers and Students

Water resistance to 50 metres makes the watch suitable for pool sessions and daily splashes. The feature set covers stopwatch timing, alarms, dual 12/24-hour display, weekday readout and hourly chimes. Buyers who need heart-rate tracking, GPS logging or smartphone notifications will not find those functions here.

50 Metre Water Resistance

The 50 m rating is the single spec that decides whether this watch matches the buyer's aquatic plans. It supports surface swimming but is not rated for diving or high-velocity water sports. If the intended use stays at or below that depth, the 9109 fits; otherwise a higher-rated model is required.

Questions about this item

Does the electronic movement need a battery change that would interrupt all-day use?

The watch runs on a sealed electronic module; no daily winding or charging is required, and the 31.2 g weight adds no noticeable wrist fatigue during continuous wear.

What strap attachment does the 9109 use so I know if my existing spring bars fit?

The 21.5 mm plastic strap is moulded to the 38.8 mm case with a fixed pin-buckle clasp, so standard spring-bar bands cannot be swapped in.

Will the 304 stainless steel case back react with my older nickel-plated buckles if I wear them together?

The case back is thick 304 stainless steel and the supplied buckle is also stainless steel; both are corrosion-resistant and will not galvanically react with legacy nickel hardware.
