Strap for PR 100 Quartz 38 Titanium / Grey / Bracelet

The lug width of the Tissot PR 100 T049.410.44.067.00 is 20mm. This dimension is measured internally, between the two rigid spring bars integrated into the case. It is the free space into which the strap sits, critical to avoid excessive play or mechanical strain. All Milano Straps straps in 20mm are compatible with this specification.

For the PR 100 T049.410.44.067.00, we recommend alligator in cognac or black (formal), vegetable-tanned calf for patina development over time, grey or black NATO for casual versatility, and black rubber for water resistance. Choice depends on use case: formal contexts suggest exotic leathers, daily sportive use suggests NATO or rubber, marine environments suggest rubber.

Remove the original strap by positioning the watch in a holder, locating the lug attachments on the case, using a spring bar tool (small lever tool) to compress the internal springs of the lugs, and extracting the strap. Verify that the lugs are intact. Thread the new 20mm strap into the lugs, ensuring that the internal spring regains tension on both sides. Do not force: the strap should slide with slight resistance.

Yes, any strap with a 20mm lug width is compatible with the PR 100 T049.410.44.067.00, as the lug width is standardised. However, verify that the total thickness of the strap does not exceed 3mm, otherwise it may create excessive friction in the spring bars. Milano Straps manufactures straps calibrated to this tolerance.

A quality vegetable-tanned leather strap, worn daily, typically lasts 2–3 years before replacement is required. Wear factors: sun exposure (accelerates ageing), humidity (promotes softening), salty perspiration (corrodes fibres). Maintenance: clean with soft damp cloth, apply leather balm every 4–6 months, avoid prolonged submersion. A NATO or rubber strap lasts 4–5 years.
