Strap for Spring Drive Titanium / White / Bracelet

The lug width (misura ansa) of the SBGA347 is 20mm. This dimension is critical when selecting a compatible strap. Measure the internal diameter of the space between the lugs using a digital calliper. Most artisanal strap manufacturers offer models specifically designed for this size, which represents a widely available standard.

For the SBGA347, we recommend alligator leather with natural irregular grain for formal elegance, vegetable-tanned calf leather for developing patina over time, or shell cordovan for those desiring tactile density and natural lustre. Choice depends on intended use and personal aesthetic preference. Artisanal leather straps enable customisation of width and colour.

The SBGA347 uses a standard removable spring bar system. Required tools: a spring bar remover (pin remover tool) or small flat lever. Position the watch on a stable surface, locate the small lateral hole on the lug, insert the tool gently to compress the internal spring pin, then extract the strap. Repeat on the other side. The operation requires approximately 5 minutes and can be performed independently or by a qualified watchmaker.

Yes, any strap with a 20mm lug width is theoretically compatible with the SBGA347, provided the total width at wrist (shoulder width) is proportionate. A quality artisanal 20mm strap will have shoulders of 18-20mm to fit the lugs perfectly. Always verify technical specifications with the supplier. Custom straps from ateliers such as Casati Milano guarantee certified compatibility.

A quality leather strap (alligator, calf, shell cordovan) under daily wear has an average lifespan of 3-5 years, variable depending on frequency of wear, climatic conditions, and maintenance level. Vegetable-tanned leather develops natural patina and improves aesthetically over time. To extend lifespan, avoid prolonged water exposure, keep the strap clean and dry, and consider rotation with other models to reduce concentrated wear.
