Strap for Automatic Hi Beat 36000 V.F.A. Platinum / White / Strap

The lug width of the Grand Seiko SBGH265J is precisely 20mm. This measurement is determined by calculating the internal distance between the case lugs where the strap attaches. It is essential to verify this specification when selecting a compatible strap, as even minor variations (18mm or 22mm) would result in an imprecise fit and misalignment with the case mounting points.

For a platinum SBGH265J, Nile alligator represents the most appropriate choice from both aesthetic and functional perspectives. The natural grain of crocodile leather creates subtle reflections that harmonise with the platinum case's patina, whilst the leather's anatomical structure ensures superior durability. Alternative premium options include vegetable-tanned calf leather and shell cordovan, both acceptable if you prefer visible ageing and chromatic personalisation over time.

To change the strap, use a dedicated spring bar tool to gently compress the internal springs of the lugs, releasing the metal ends from the case mounting points. Insert the new strap by positioning one end in its corresponding lug seat first, then compress the opposite lug until the second end locks with an audible click. Avoid forcing to prevent damage to the platinum case; if inexperienced, Casati Milano atelier provides this service with execution warranty.

Yes, any strap with a certified 20mm lug width is compatible with the SBGH265J, regardless of manufacturer. Compatibility is guaranteed by standardised measurements; however, it is recommended to select premium materials (alligator, shell cordovan, excellent-quality calf) to preserve aesthetic coherence and temporal value of your platinum timepiece. Bespoke straps crafted from carefully selected leathers with hand-stitching demonstrate superior longevity and colour evolution compared to industrial products.

A premium leather strap (alligator, cordovan, vegetable-tanned calf) subjected to daily use with appropriate maintenance can last 5-8 years before requiring replacement; if worn occasionally, the lifespan extends to 10-12 years. Longevity depends on: frequency of use, exposure to moisture and chemical agents, and periodic preventative treatment with specific leather creams. Bespoke straps constructed with double hand-stitching demonstrate superior resistance to industrial examples, as each stitch is reversible and can be reinforced without compromising the leather's structural integrity.
