The dial has a 12-hour scale and a smaller 24-hour scale for military time. The hour and minute hands are filled with SuperLuminova as are the 5-minute markers around the dial. The brushed stainless steel case is a very wearable 39mm in diameter and it is 12mm thick. Lug to lug (or tip to tip) measurement is 48.5mm. The crown is a signed screw-down type that enables a better water resistance rating of 100-meters. 

Inside the case is an NH36A, 24-jewel automatic movement with 21,600 vibrations per hour. This self-winding movement supports hand winding and hacks (seconds hand stops when you pull out the crown). Power reserve is about 41 hours fully wound. You can view the movement via an exhibition-window (screw-down) caseback.

The ISL-129 has an innovative day and date display viewed at 6:00 on the dial. Due to the configuration of the day wheel, there is only one language (English). You will note that the dial has excellent visibility due to the use of an anti-reflective sapphire crystal that also guards against scratches.

This model comes with a khaki color woven nylon strap with leather backing and a signed stainless steel buckle. The strap comes with quick-release pins so you can change up the look with another strap without the need for any special tools. Just use your index finger.
