Spring Drive SBGA362— lug 20mm

The SBGA362 lug width measures 20mm. This standard width ensures compatibility with a vast range of aftermarket artisan straps, guaranteeing seamless integration without requiring any structural modifications to the case.

For a yellow gold model such as the SBGA362, we recommend an alligator strap in black or cognac brown, alternatively a shell cordovan strap in burgundy. These premium materials elevate the watch's intrinsic quality and aesthetic identity. Avoid synthetic materials or low-grade chrome tanning.

Strap replacement involves removing the lug pins—the small metal cylinders securing the strap in place. Use a dedicated tool such as a spring bar removal tool or a precision screwdriver. Proceed cautiously to avoid damage to the case lugs. Should you lack experience, consult a qualified watchmaker.

Certainly. The SBGA362 accommodates any strap featuring a 20mm lug width. Artisan leather straps—alligatore, shell cordovan, or vegetable-tanned calf—integrate flawlessly and offer construction quality comparable to the timepiece itself, significantly enhancing overall aesthetic value.

A high-quality vegetable-tanned leather strap typically lasts 3–5 years of regular wear, developing a distinctive patina that reflects the wearer's personal history. Shell cordovan, owing to its structural density, may extend 7–10 years of active use. Regular maintenance—gentle cleaning and occasional conditioning—substantially prolongs longevity.
