SOLAR POWERED — NO BATTERY SWAPS, EVER — Casio's solar-recharging system converts even faint light from fluorescent lamps into ample energy to achieve stable operation of various high-load functions — meaning the MTP-S120L stays powered through normal indoor and outdoor use indefinitely. Operating time from a full charge runs approximately 8 months without any additional light exposure, making it one of the most maintenance-free everyday analog watches available.

STAINLESS STEEL CASE WITH MILITARY-INSPIRED NYLON STRAP — The 42mm stainless steel case features a solid caseback and fixed bezel, paired with a 22mm nylon NATO-style strap with a buckle closure. The fabric band has a backing just like a proper military strap — a purposeful, field-watch aesthetic that pairs naturally with the black or olive colorways and fits the 22mm lug width for easy strap swaps.

DAY & DATE DISPLAY | 24-HOUR INNER BEZEL | LUMINOUS HANDS — The black dial features hour, minute, and second hands, a day and date display, and a 24-hour inner chapter ring. Luminous hands ensure readability in low-light conditions — a practical field-watch detail that keeps the time visible after dark without a backlight. Mineral glass protects the dial from everyday scratches.

100M WATER RESISTANT | SCREW-ON CASEBACK | 42MM STAINLESS STEEL — Water resistant to 100 meters (10 ATM), with a stainless steel case measuring 42mm in diameter. The caseback is screw-on, providing additional movement protection — a construction detail typically found on watches at a significantly higher price point. Push-in crown completes the clean, purposeful profile.

FIELD-WATCH VERSATILITY — NATO STRAP-READY & EVERYDAY CAPABLE — The MTP-S120L is great for a grab-and-go everyday watch — stainless steel case, solar powered, day/date, and thin enough where a NATO strap doesn't make it look too thick on the wrist. Available in Black (MTP-S120L-1AV) and Green (MTP-S120L-3AV) colorways — both built on the same proven solar platform.
