Strap for Heritage Collection 60th Anniversary Limited Edition

The Grand Seiko SLGH002 features a lug width of 20 millimetres. This is the distance between the two lugs where the strap attaches. You can verify this measurement by measuring directly across the case with a ruler or digital calliper. This dimension is standard for mid-sized watches and accommodates any quality aftermarket strap manufactured to 20mm specifications.

Alligator leather in vegetable tanning remains the natural choice: the Madras or Nile grain texture creates a formal dialogue with the case geometry, whilst dark brown natural colour does not compete chromatically with yellow gold. Alternatively, English calf leather in vegetable tanning offers fine grain and patina that ages nobly over time. Shell cordovan from English cobblers represents a premium option for those who appreciate accelerated leather ageing.

Remove the strap using a spring bar tool or small hammer and punch. Locate the tiny coil springs inside the lugs, insert the tool into the narrow channel, then lift slightly to relieve spring tension. The strap slides out sideways. To install a new strap, reverse the procedure: align the lugs with the holes, insert the spring, and secure it in place. This procedure requires care to avoid scratching the yellow gold case.

Yes, any strap constructed to 20mm specifications is compatible with the Grand Seiko SLGH002. Compatibility is guaranteed by identical lug width. However, material selection significantly impacts final aesthetics: for a yellow gold case, noble leathers (alligator, shell cordovan, calf in vegetable tanning) are recommended, paired with austere finishes that do not compete chromatically with precious metal.

A quality leather strap (alligator, shell cordovan, calf in vegetable tanning) subjected to daily wear has an average lifespan of 4-6 years before replacement is required. Durability depends on ambient humidity, frequency of wear, strap maintenance, and the type of tanning used. Vegetable-tanned leathers tend to age nobly, developing patina that can extend aesthetic appeal beyond the functional threshold. Casati Milano offers an 18-month warranty on all custom-made straps.
