NATO & Rubber Straps

NATO and rubber straps are the go-to for modders who value comfort and durability. Originating from military designs, NATO straps offer quick-change functionality and safety — if one spring bar fails, your watch stays secure. Rubber, on the other hand, is perfect for divers and outdoor enthusiasts who wear watches daily. Builders pairing Seiko NH35 or ST Series movements with sporty cases love this combination for its versatility and waterproof resilience.

Our guide Choosing the Best NATO & Rubber Straps explains how to find the right fit and length. For installation, use spring bar tools and check the fit with matching buckles & clasps. Keep your straps fresh by cleaning them weekly using microfiber cloths and mild soap. For advanced builders, custom silicone color options are available under Custom Watch Part for a personalized finishing touch.
