The Singapore based Gruppo Gamma Venturo Field III is a modern take on the legible 3-hander military style watch. The comfortably sized 40mm diameter case on a steel bracelet makes it a solid companion for the trenches and valleys of the typical week. Swap it out to the rugged khaki canvas strap for a casual weekend look. This should be a cinch with the built-in quick release springbars on the bracelet and included tool for the strap.

About the Movement:
TMI/SII (Seiko) caliber NH38A
For all intents and purposes, the TMI (Time Module Inc.) / SII (Seiko Instruments) caliber NH38A is the no-date version of one of the most popular automatic watch movements in the world: the NH35A. Before the NH38A was introduced, NH35A powered microbrand watches would have a phantom date position - this is when the dial of the watch does not have a calendar window, but the watch still has a date setting mode (second click of the crown). The NH38A gives you the solid workhorse performance of the NH series, but with a clean 3-hands look.
Movement Type:
Automatic, self-winding mechanical movement. This watch is powered by the movement of your wrist, so you don't have to worry about replacing batteries every year or two!
FAQ:
Can you overwind it by wearing it too much? No! The more you wear it, the better it will run. Watches worn with a full power reserve will give you the best results. Wear it and enjoy it!

Quick Specs:
- Jewels: 24
- Power Reserve: 41 hours
- Beat Rate: 21,600 bph
- Hacking? Yes. This means the seconds hand stops when the crown is pulled out in time-setting mode. Some collectors have come to appreciate this feature because it allows for more precision when setting the time.
- Hand-Windable? Yes. Although this is an automatic movement, it can also be wound by hand using the crown.
