Strap for Bellflower Square Yellow Gold / Diamond / Bracelet

The lug width is 18 mm. This measurement represents the distance between the two horizontal pins protruding laterally from the case. It is essential to measure this width precisely before purchasing an aftermarket strap, as an strap with a different width (such as 16 mm or 20 mm) would result in proportional incongruence and poor wrist fit.

For the Bellflower in yellow gold, the ideal strap is in natural alligator or shell cordovan, in dark brown, cognac, or burgundy tones. These materials and colours amplify the aesthetic character of the gold without appearing excessive. Alternatively, vegetable-tanned calf leather offers a more restrained yet equally elegant option, whilst NATO fabric straps are perfect for daily summer wear without compromising durability.

The Bellflower T74.3.308.71 uses a spring bar system. To change the strap, a specialised tool (spring bar removal tool) is required to press inward the small spring located within each pin. Once the spring is released, the pin will slide out of the case easily. Proceed with caution to avoid scratching the yellow gold. If you do not possess the tool, it is advisable to consult a professional watchmaker or a specialist strap replacement service.

The lifespan of a leather strap depends on the material, frequency of use, and maintenance. A high-quality alligator or shell cordovan strap, used daily, maintains integrity and aesthetics for 5-7 years. Vegetable-tanned calf typically lasts 4-6 years. Shell cordovan, due to its dense fibrous structure, can exceed 10 years of useful life if properly maintained. Regular maintenance (avoiding prolonged moisture, occasionally applying a specific conditioner) significantly extends lifespan. NATO fabric straps have superior durability in humid environments.
