Roma WRO17MA26SS01AA— lug 20mm

The lug width is 20mm. This standard ensures the best proportions relative to the 42mm case diameter. Verify the measurement by checking the internal distance between the two metal lugs that insert into the watch's strap holes.

Selection depends on intended use. Dark alligator (chocolate brown or black) emphasises the case's geometric-brutalist character. Vegetable-tanned calf develops a fascinating patina over time. Heavy canvas NATO transforms the Roma into a field instrument. FKM rubber offers superior durability for high-intensity daily wear.

Remove the old strap by gently pushing the lug inward until the first attachment releases. Extract the strap completely. Insert the new strap, aligning the lugs with the watch's strap holes, and slide until you feel mechanical engagement. Ensure the strap sits flush on both sides before wearing.

Yes, any strap with a 20mm lug width is mechanically compatible. We recommend verifying that the final lug matches the case's strap holes exactly to avoid unwanted play. Milano Straps are calibrated to these specifications and guarantee perfect fit.

Durability depends on tanning method and intensity of use. Vegetable-tanned calf maintains optimal structure for 3–5 years with regular maintenance (cleaning and hydrophobic treatment biannually). Alligator, with more resistant fibres, exceeds 5 years. In humid environments or with continuous use (swimming, sports), consider rotating between multiple straps.
