Strap for Aquaracer Professional 200 Solargraph 40 Stainless Steel / Black

The lug width is precisely 20mm. Measure internally between the attachment points to the case using a digital calliper. Do not confuse this with external measurement, which will yield a slightly higher value (approximately 21–22mm). Only the internal measurement of 20mm guarantees correct compatibility with artisanal straps.

The choice depends on usage and aesthetic preference. Alligator in dark blue or black offers refined elegance and exceptional durability. Vegetable-tanned calf leather delivers character and natural patina over time. Rubber or silicone ensures practicality and water resistance for intensive sporting contexts. Technical fabric NATO is ideal for a versatile, casual aesthetic.

The WBP1114.BA0000 features standard straight lugs with a 20mm width. Use a spring bar tool to compress the internal spring-bar pin at the lug, slide the old strap outward, and insert the new strap by pushing until you feel the tactile click of the pin seating. Handle carefully to avoid damaging the case edges. If uncertain, consult a professional watchmaker.

Yes, provided the internal lug width measurement is precisely 20mm and the strap is manufactured with appropriate thickness (typically 3.5–4mm at the base). Quality artisanal straps guarantee complete compatibility and often deliver superior comfort compared to the original bracelet, with options for personalisation in leather types, colours, and thread.

A quality leather strap with vegetable tanning typically lasts 3–5 years with intensive daily use. Alligator models easily reach 7–10 years due to the inherent strength of the hide. Longevity depends on exposure to moisture, perspiration, and sunlight. With preventative maintenance—such as annual conditioning—lifespan increases significantly.
