Strap for Spring Drive Chronograph Titanium / Ceramic / Blue / Bracelet / Black Ceramics Collection

The lug width of the SBGC219 is precisely 20mm. This dimension is critical for mechanical and visual compatibility with aftermarket straps. Measurement should be taken between the lug holes, excluding any bezel protrusion. Maximum recommended tolerance: ±0.5mm.

Alligator in vintage finishes is the primary aesthetic choice, as the natural grain harmonises with the Zaratsu-polished surfaces of the titanium case. For durability and patina development, shell cordovan offers exceptional resistance and colour evolution. Full-grain leather with vegetable tanning provides an excellent balance between elegance and daily versatility. For aquatic environments, structured FKM rubber maintains aesthetic coherence with the chronograph's sporting profile.

The SBGC219 uses spring-pin lug bars, not standard push-pins. To remove the old strap, insert a flat tool under the spring and gently compress to release the pin. This operation requires experience: we recommend entrusting the task to a skilled watchmaker to avoid scratching the titanium case. Replacement with an artisanal 20mm strap from Milano Straps can be professionally fitted at the Casati atelier.

Yes, all 20mm lug width straps are mechanically compatible. However, the SBGC219's precision engineering demands very tight tolerances. Artisanal straps from Milano Straps guarantee precise dimensions and construction quality consistent with the watch. We advise against economy-grade straps, which may present dimensional inconsistencies and compromise overall aesthetics.

A quality artisanal leather strap (alligator, calf, shell cordovan) with vegetable tanning typically lasts 3-5 years with moderate daily use, developing beautiful patina over time. Alligator and shell cordovan, owing to their thicker structure, can reach 5-7 years. Wear concentrates on the strap's flex zones and pass-through edges. Milano Straps offers an 18-month warranty and refurbishment services to extend strap lifespan.
