Strap for Portugieser Chrono-Automatic Rose Gold / Black / Diamond

The lug width of the IW3714-28 is 20 mm. This is the internal distance between the two integrated lugs on the case. Any compatible strap must respect this width to ensure proper fitting and eliminate play between the strap and the watch lugs. An incorrect width compromises both the aesthetics and functionality of the junction.

To enhance the rose gold case of the Portugieser, we recommend an alligator strap in black or dark brown, or calf leather with vegetable tanning that allows for an evolving patina over time. Shell cordovan is ideal for those seeking a surface with slight intrinsic lustre. Rose gold will dialogue better with dark tones and natural materials rather than synthetic finishes.

The strap is changed by extracting the lateral pins (spring bars) from the lugs using a specific tool called a spring bar removal tool. Insert the tool into the lateral slots of the pins, apply gentle pressure and the pin will retract, freeing the strap. Proceed with caution to avoid scratching the case. If you are not experienced, entrust the task to a professional watchmaker.

Yes, any strap with a 20 mm lug width is compatible with the IW3714-28, regardless of brand. High-quality artisanal straps made from alligator, calf or shell cordovan often offer superior construction characteristics and materials compared to original accessories. Always verify that the strap is crafted by specialised artisans to guarantee precision in measurements.

The lifespan of a leather strap depends on the intensity of use, the type of tanning and the quality of craftsmanship. Quality vegetable-tanned calf, worn daily, lasts an average of 3-5 years before requiring replacement. Shell cordovan, thanks to its extraordinary durability, can last 7-10 years. Alligator falls within this range. Regular maintenance and alternating with other straps significantly extend longevity.
