Strap for Seamaster PloProf Co-Axial Only Watch

The Omega Seamaster PloProf 224.62.55.21.04.001 features 24mm lug width. This lug width measurement is specific to the model due to the substantial 55mm case. When measuring lug width, do so on the underside of the case from lug to lug, excluding the center passant. Compatible straps must be certified 24mm to ensure a perfect fit.

Nile alligator with medium grain is the historical choice for the PloProf. The uniform texture does not compete with the aggressive case geometry. For an artisanal option, vegetable-tanned calf creates an aged patina that blends the rose gold tone over time. Shell cordovan is ideal for extreme durability (5–7 years) without structural failure.

Changing the PloProf strap requires a specific tool (lug spring bar removal tool) or fine tweezers. Place the watch face down on a soft surface. Locate the lug shoulders and gently push inward to release the pin. Remove the used strap and insert the new 24mm strap, ensuring the pin clicks into place on both sides.

Yes, any aftermarket strap certified as 24mm lug width is compatible with the Seamaster PloProf 224.62.55.21.04.001. Verify that the supplier clearly specifies 24mm (not 22mm or 26mm) and that the lugs do not present notches or specific profiles that require OEM straps only.

A quality artisanal alligator strap lasts 3–4 years with ordinary wear. Vegetable-tanned calf ages visibly within 12 months and maintains structure for 2–3 years. Shell cordovan is the longest-lasting material, exceeding 5–7 years if rarely exposed to fresh water. If you wear the PloProf in frequent saline or aquatic environments, prefer NATO Seagull canvas or fluorosilicone rubber, which do not deteriorate.
