Heavy-Duty Mud-Resistant Watch
The Casio TRT-110H-3AV is a digital quartz watch built for demanding environments. Its mud-resistant construction and 100-metre water resistance make it suitable for swimming and snorkeling. A 10-year battery reduces maintenance, while the super illuminator LED ensures readability in darkness. Dual time zones and a full auto-calendar up to 2099 support travel and long-term planning.
Built for Outdoor and Tactical Use
This watch suits professionals and enthusiasts who need reliable timekeeping in mud, water or low light without audible alarms. The vibration alert provides discreet notifications for field work or quiet settings. Buyers who want a slimmer profile or a traditional analogue display should look at something else. The 47.9mm case diameter and resin strap prioritise function over formal aesthetics.
Sustained Reliability in Harsh Conditions
Mud resistance and 100-metre sealing maintain performance during prolonged exposure to debris and moisture. The 10-year power source eliminates battery swaps over a decade of daily wear. Super illuminator output remains consistent for night navigation, and the vibration motor operates without the degradation that affects piezoelectric buzzers. Auto-calendar accuracy holds without manual correction until 2099.

Questions about this item
Does the TRT-110H-3AV need a smartphone link for its dual-time or calendar functions?
No. The watch runs its dual-time display, full auto-calendar to 2099, stopwatch and countdown timer entirely on the quartz movement.
Can I keep wearing my older 100 m Casio while swimming alongside this new 100 m model?
Yes. Both are rated to 100 m (330 ft), so each is suitable for swimming and snorkelling but not for diving.
How do I confirm the vibration alarm and Super Illuminator are working after I put the watch on?
Trigger an alarm in a quiet room — you should feel a distinct buzz on the wrist — then press the light button in darkness; the Super LED should flood the whole dial.
