Frequently asked questions
What is the lug width of the IWC Da Vinci IW3754-07?
The lug width of the Da Vinci IW3754-07 is 20 mm. This dimension is standard for wristwatches of this category (41.50 mm case diameter) and is essential when selecting any compatible strap, whether aftermarket or bespoke.
Which strap is recommended for the platinum Da Vinci IW3754-07?
For the platinum Da Vinci we recommend alligator in black or deep brown, or vegetable-tanned calf leather for natural colour evolution over time. A grey anthracite rubber strap with titanium deployante is ideal if you wish to emphasize the chronograph rattrapante's sporty character. The choice depends on intended use and personal aesthetic preference.
How do you change the strap on an IWC watch with 20 mm lugs?
The strap is replaced by removing the spring bars that secure the lugs to the case. Using a dedicated spring bar removal tool, compress the internal pin, extract the old strap, and insert the new one, ensuring the spring bar clicks securely into both seats. If unfamiliar with the procedure, have a qualified watchmaker perform the replacement.
Is an aftermarket strap compatible with the Da Vinci IW3754-07?
Yes, any strap or bracelet designed for 20 mm lug width is completely compatible with the Da Vinci IW3754-07. A wide range of materials is available online: alligator, calf leather, shell cordovan, certified rubber, and technical textiles, all customizable in width, stitching, and initials.
How long does a natural leather strap last on a wristwatch?
A quality leather strap worn daily typically lasts 3-5 years. Factors such as tanning method (vegetable or synthetic), ambient humidity, frequency of use, and maintenance significantly influence longevity. Vegetable-tanned leather develops a natural patina and ages elegantly; with regular care it can last beyond 5 years.
