Strap for Portugieser Chrono-Automatic Stainless Steel / Silver

The lug width of the Portugieser IW3714-65 is 20 mm. This dimension is calibrated to the proportions of the 40.90 mm case and is critical for correct fitting and mechanical integrity of the strap. Always verify the measurement before ordering.

Alligator is the authentic choice: fine texture, natural patina over time, and direct aesthetic dialogue with the stainless steel case. Vegetable-tanned calf is the versatile alternative; shell cordovan for those seeking magnificent aging. Avoid rubber and technical textile, which diminish the constructive identity of the model.

We use 20 mm spring bars. Procedure: depressurize the spring with a dedicated tool, extract the bar from one side, remove the old strap, insert the new one through the lugs, and reinsert the spring bar. If inexperienced, we recommend intervention by a certified watchmaker.

Yes, any 20 mm strap is compatible with the Portugieser IW3714-65 provided the lug slots respect the width. To maximise aesthetic and functional fidelity, we recommend artisanal leather straps of premium grade, which maintain constructive coherence with the caliber 79350 movement.

Durability depends on material and usage. Alligator and shell cordovan: 5-8 years with regular wear. Calf: 3-5 years. Vegetable tanning allows reconditioning via restoration. Critical factors: sun exposure, humidity, frequency of strap changes, quality of stitching. Artisanal straps guaranteed for 18 months.
