Ultra-Thin Profile: Our unique 3-ring single-pass design significantly reduces the gap between the watch head and wrist, offering a sleek, sophisticated look with a streamlined fit.
Enhanced Durability: By eliminating the buckle spring bar found in most straps, our design minimizes points of failure, providing reliable performance and peace of mind during any activity.
Premium Materials: Crafted from durable, UV-resistant, and water-resistant bonded nylon, our strap ensures long-lasting performance. Complemented by robust stainless steel hardware, it promises both strength and longevity.
Superior Comfort: The reduced bulk and improved fit of our strap offer exceptional comfort for all-day wear—whether you’re at the office, enjoying a night out, or engaging in extreme sports.
Versatile Design: Compatible with any watch equipped with spring bars (excluding smartwatches), our strap combines traditional style with modern improvements in functionality and comfort.
Precise Fit and Sleek Appearance: Available in three widths (18mm, 20mm, and 22mm) and three lengths (small, medium, and large), our strap minimizes visible adjustment holes by spacing them closer together. This design not only keeps adjustment holes out of view when tucked but also allows for a more precise fit.
Dimensions: With a slim 1mm thickness and low-profile metal keepers featuring an internal height of 4.4mm, our strap achieves a streamlined and aesthetically pleasing appearance.

Good solid straps and the watch sits closer to the wrist
Good solid straps and I really like that they have designed something that allows the watch to sit closer to the wrist. Takes a bit of getting used to the first time but gets easier. I would prefer much softer material and of course some more colours would be great

GREAT STRAPS
great quality, nice looking. I have a little trouble getting them adjusted and buckled. I'm 73, probably a lack of dexterity.

Just what my GSAR needed
My marathon GSAR is a chonky boi in height. So using a SIFU strap leaving only one thin strap between my wrist and the caseback helped it fit much closer to the wrist. It’s the perfect combo. Thanks for making a great product!
