Quartz movement with calendar function
The allentian 1801 uses a quartz movement to keep time and display the date. A black dial and black strap give it a uniform look. The case measures 40mm wide and 8mm thick, while the strap is 20mm wide and 250mm long. It suits daily wear where simple time and calendar readings are needed.
Upgrade from basic time-only watches
This model adds a calendar window so the date is visible at a glance. The jump is worth it when you want both functions without extra buttons or sub-dials. A zinc alloy case and glass mirror protect the movement. Choose the leather strap at 36g or the stainless steel strap at 84g depending on preferred weight.
Practical limits of 30m water resistance
The 30m rating covers splashes, rain and brief immersion such as hand washing. It is not intended for swimming, showering or diving. Pressing buttons while wet can compromise the seal. Leather straps may degrade faster with frequent water contact, so the steel option is more durable in damp conditions.

Questions about this item
What is the case diameter and thickness for wrist fit?
The case is 40mm wide and 8mm thick, so measure your wrist to confirm it sits comfortably.
Does the 20mm strap use spring bars or a fixed lug design?
The 20mm strap attaches with standard spring bars; compress the bar fully before sliding it into the lug holes to avoid scratching the zinc-alloy case.
How often should the quartz movement battery be replaced?
Replace the button cell when the calendar or time display slows; a watchmaker can swap it and pressure-test the 30m water resistance at the same time.
