SEIKO · SND379R · MILITARY CHRONOGRAPH · 7T92 QUARTZ · 100M WR · NAVY DIAL · NYLON STRAP
The chronograph Japan's officers reach for.
Quietly capable. Honestly priced.
A 38 mm SEIKO chronograph with a navy dial, a compass-marked bezel, and a tough nylon strap — the kind of watch that has quietly earned a following among Japanese self-defense and police personnel as a personal-issue piece. The 7T92 quartz movement runs a 1/20-second stopwatch, a 12-hour counter, and a date window, all behind 100 m water resistance. A no-nonsense field chronograph at a no-nonsense price.

⚠ BEFORE YOU BUY — PLEASE CHECK
Reimported overseas model. The SND379R belongs to SEIKO's "Overseas Model" line — manufactured for export markets and sold back into Japan through licensed distributors. Country of manufacture is not stamped "Made in Japan." It is a 100% genuine SEIKO product with the standard SEIKO international warranty.
Warranty. SEIKO international 1-year manufacturer warranty applies. Servicing should be carried out at any authorized SEIKO service center worldwide.
Compass bezel is decorative. The N/E/S/W markings on the bezel are reference markings, not a magnetic compass. To take a bearing, use the sun-and-hour-hand method against the rotating bezel.
Wrist size. 38 mm is on the smaller side of modern men's watches but classic by historical standards. Sits well on wrists from 6.0" to 7.5".
Battery. Standard silver-oxide cell — replaceable at any watchmaker. Estimated life ~3 years with normal chronograph use.
Why this one
🪖
A quiet cult watch in Japan
The SND379R has built a steady following among Japanese self-defense personnel and police officers as an affordable, no-fuss field chronograph. Tough, legible, replaceable.
⚙️
SEIKO's 7T92 movement
The 7T92 is one of SEIKO's most refined quartz chronograph calibers — 1/20-second precision, ±15 sec/month, and a reputation for running for decades on a steady diet of battery changes.
💧
100 m, screw-back
Solid screw case back and 10 ATM water resistance. Confidently swimmable, splash-proof, rain-proof — built for the way an actual field watch gets used.
🧭
Compass-marked bezel
A directional bezel that pairs with the hour hand for sun-based bearing estimation — a classic field-craft touch that gives this watch its identity.
📏
Honest 38 mm
A classically-sized case at 38 mm and only 10 mm thick. Slips easily under a cuff, sits well on smaller and average wrists, and looks proportioned the way a tool watch should.
🪡
Pass-through nylon strap
The single-piece nylon strap means even if a spring bar fails, the watch stays on your wrist. A small detail with a long history in military issue watches.
