Strap for Portuguese Automatic Red Gold / 100 Years Hübner

The Portugieser IW5001-28 requires a strap with a 22-millimetre lug width. This is the distance separating the two lugs (or baionette attachments) on the case. To verify the exact measurement, use a digital calliper, positioning it between the two holes where the attachments insert into the case.

For a rose gold Portugieser, Mississippi alligator in tabac or cognac tones is the premier choice: the fine grain and natural patina create chromatic harmony with the warm gold. Equally distinguished alternatives include dark brown shell cordovan, which develops a deep patina over time, or vegetable-tanned calf leather in natural tones, creating an elegant contrast with the rose-coloured metal.

The Portugieser IW5001-28 employs baionette attachments, a system wherein the attachments slide within grooves present on the case. To remove the original strap, grip both ends and pull in opposite directions; insert the new strap by aligning the attachments with the grooves and slide until locked. No specialised tool is required, though a rubber pad helps avoid scratching the case.

Yes, provided the strap is equipped with baionette attachments (or is adaptable via a conversion kit) and presents a 22-millimetre lug width. Many artisanal strap makers, including Casati Milano, produce custom straps compatible with the Portugieser, maintaining the same lug width and offering personalised choice of leathers and colours.

An alligator or vegetable-tanned shell cordovan strap, subject to moderate use (4–5 days per week), maintains full functionality for 4–7 years before replacement becomes necessary. Durability depends on exposure to moisture, perspiration and mechanical stress. A vegetable-tanned calf strap tends to wear more rapidly (3–5 years), whilst cordovan, owing to its density, can last beyond a decade with appropriate care.
