Modding 101 — Start Here

New to watch modding? You are two screws away from a watch nobody else owns. Swapping a strap is the fastest, cheapest, zero-risk mod there is — no tools beyond a spring-bar fork, five minutes, fully reversible. Start with your platform below.

Fitment guides by platform

  • GA-2100 CasiOak strap & adapter guide — which straps fit, why you need an adapter, and how to install one.
  • SKX007 / SRPD strap guide — coming this week. 22mm curved vs straight end links explained.
  • Apple Watch band size guide — coming this week. Small vs Large, Ultra fitment.

The three rules of strap swapping

  1. Match the lug width. 22mm strap on 22mm lugs — every product page on strapmod lists exact fitment.
  2. Mind the end-link shape. Curved end links hug rounded cases (SKX, Turtle); straight or integrated ends suit flat cases (CasiOak, Royal Oak style).
  3. Quick-release is your friend. All strapmod FKM and leather straps use quick-release bars — no tools, no scratches.
