Strap for PCAT

The lug width of the CB5887-55H is 23 millimetres. This specification represents the distance between the two pins securing the strap to the watch case. To verify this measurement with precision, use a digital calliper, positioning the gauge between the two lugs at their midpoint. Confirming this measurement is essential before ordering an aftermarket strap, as variations of mere tenths of millimetre would create gaps between strap and case.

The choice depends on intended usage: for formal environments, a vegetable-tanned calf leather or alligator strap enhances refinement; for sporting activities or humidity exposure, a NATO in Cordura or FKM rubber offers superior durability. Shell cordovan represents a premium option for those seeking a naturally evolving patina over time. The CB5887-55H, with its 43-millimetre case, harmonises exceptionally with straps of proportionate width relative to its 23-millimetre lug width.

The procedure requires a specific tool: a spring bar removal tool or small flat lever. Position the watch on a soft surface (microfibre cloth) with the caseback facing upward. Insert the lever into the cylindrical spring hole, applying gentle pressure to retract the pin, then extract the previous strap. Align the new strap's pins with the case lugs and press the pin into position until it clicks. If you lack the necessary tools, entrust the operation to a professional watchmaker to avoid case scratching.

Yes, any strap with an exact 23-millimetre lug width is compatible. Verify that the manufacturer specifies this dimension in the technical specifications. Numerous online retailers, including milanostraps.it, supply certified 23mm straps in diverse materials: leather, NATO, rubber, alligator. Before purchase, confirm dimensions to prevent returns.

A calf or alligator strap, when subjected to ordinary maintenance, maintains structural integrity between 3 and 7 years depending on usage intensity and humidity exposure. Vegetable tanning develops a natural patina, visually elegant yet requiring occasional treatment with specific balms. Prolonged exposure to marine humidity or salinity significantly reduces lifespan. NATO and rubber straps offer superior longevity (10+ years), although rubber may lose elasticity in extremely hot climates.
