Strap for Spring Drive 200 m Diver's Titanium / Black / Bracelet

The SBGA231 is equipped with a 20mm lug width. This dimension is specific to the model and requires straps compatible with the same width. To verify the size, position a digital calliper between the two internal attachment points of the case. Using a strap of different width would result in an imprecise fit and could damage the case lugs.

For formal contexts, we recommend an alligator strap in black or dark brown, which contrasts elegantly with the Zaratsu specular finishing of the titanium case. For daily wear, a vegetable-tanned calf leather strap in natural tones offers a balance between elegance and practicality, with the advantage of developing a patina over time. For sporting occasions, a perforated rubber strap or a woven NATO strap maintains the sportiness of the case without formal compromises.

Remove the strap using a dedicated tool (spring bar tool) to gently compress the elastic pin that secures the strap to the lugs. Once released, extract the old strap and insert the new one, ensuring that the pin locks securely in both lugs. The strap must sit flush with the case without gaps. If you are unsure, consult a professional to avoid scratching the case.

Yes, provided the strap is manufactured for a 20mm lug width. Milano Straps offers a selection of aftermarket straps of artisanal quality, constructed to the same precision standards required by a watch of this category. Always verify that the strap lugs are slightly wider than the nominal width (typically 20.5mm) to ensure a comfortable fit without play.

A high-quality leather strap (alligator, calf, or shell cordovan) has an average lifespan of 3-5 years with daily wear, depending on the tanning and care. Vegetable tanning tends to last longer than modern finishes, developing a natural patina. Exposure to direct sunlight, sweat, and humidity accelerates wear. A well-maintained strap rotated seasonally can exceed 5 years. Milano Straps offers an 18-month warranty on straps crafted by the Casati Milano atelier.
