Strap for Da Vinci Tourbillon Leonardo White Gold / English

The lug width of the IWC Da Vinci IW3752-23 is 19mm (measured from inner wall to inner wall). This non-standard intermediate dimension is a deliberate design choice by IWC to achieve optimal proportions with the 39mm case diameter. To verify compatibility with any aftermarket strap, measure the internal space between the lugs at the widest point using a digital calliper.

For the Da Vinci IW3752-23 in white gold, alligator leather is the classic choice: its uniform grain pattern accentuates the brilliance of the precious metal without visual competition. Dark navy or chocolate brown variants work exceptionally well. Alternatively, vegetable-tanned calf leather introduces warmth and develops character over time, or shell cordovan for a subtle sporty edge whilst maintaining formality. Satinised FKM rubber remains the most versatile solution for daily wear in informal contexts.

The Da Vinci IW3752-23 uses spring bar attachments. Procedure: place the watch on a soft surface (microfibre cloth), locate the small hole beneath the lug, insert the tip of a spring bar removal tool, press inward to compress the spring, and slide the strap outward. Repeat on the opposite lug. To install the new strap, align the strap lugs with the watch holes and press the bar until you hear a click. If inexperienced, entrust this operation to a professional watchmaker.

Any strap featuring a 19mm lug width is mechanically compatible with the Da Vinci IW3752-23. Ensure the total strap length suits your wrist (typically 75-110mm for medium to large wrists). MilanoStraps offers a comprehensive selection of 19mm straps, fully customisable in leather (alligator, calf, shell cordovan), rubber and fabric, all tested for mechanical and aesthetic compatibility with the Da Vinci. Personalisation options include initials and custom stitching thread colours.

Leather strap longevity depends on tanning quality, thickness and usage intensity. A quality alligator strap (1.4–1.6mm thick) withstands 3–5 years of daily wear; shell cordovan extends to 5–7 years due to its fibrous, rigid nature. Vegetable-tanned calf leather, more delicate, lasts 2–3 years with regular use. All materials develop patina and character over time. To extend lifespan, avoid prolonged water exposure, dry immediately if wet, and rotate between multiple straps to reduce mechanical stress. MilanoStraps leather straps include an 18-month warranty against manufacturing defects.
