Strap for Da Vinci Perpetual Yellow Gold / White / Italian / Bracelet

The lug width (lug-to-lug distance) of the IW9252-02 is precisely 19 millimetres. This measurement represents the space between the two spring bar attachment points on the case and determines which category of artisanal strap is compatible. To measure accurately, position the calliper perpendicularly between the lugs, considering only the internal space without the case material thickness.

For this white gold model we recommend alligator (most formal and luminous choice), vegetable-tanned calf leather (which develops visible patina over time), or shell cordovan in dark tones (burgundy, cognac) for elegant contrast. Your selection depends on usage context: alligator for formal occasions, calf for refined everyday wear, shell cordovan for sophisticated versatility. All combinations require a robust deployant clasp, preferably in matching white gold.

The strap is replaced by gently removing the two spring bars (springbars) that connect the strap to the case lugs. Use a specialised springbar tool to apply precise pressure without scratching the white gold case. Insert the spring bar into the new strap, aligning it perfectly with the case lug recesses. If the caseback is transparent, exercise care to avoid rotating the spring bars directly above the movement. For cases in precious materials, consider having the operation performed by a qualified watchmaker.

Yes, provided the lug width is exactly 19 millimetres. Aftermarket compatibility on the Da Vinci is guaranteed by standard spring bar dimensions. However, for a timepiece of this category (chronograph perpetual calendar in white gold), we recommend straps crafted by specialised artisans: the construction quality, leather selection, and clasp finishing must reflect the technical level of the case itself.

A high-quality leather strap (alligator, natural calf, shell cordovan) with vegetable tanning maintains structural integrity for 3 to 5 years of regular wear. Lifespan depends on humidity exposure, perspiration, frequency of wear, and temperature fluctuations. The advantage of natural leather is that it develops visible patina, leaving a tangible record of time passing. Shell cordovan straps tend to last slightly longer due to material density. To maximise lifespan, rotate with alternative straps and occasionally apply leather-specific conditioner.
