Strap for TT1 Worldtimer Stainless Steel - Rubber / Black / Bracelet

The Oris TT1 reference 01 690 7527 4464-07 8 24 01P features a lug width of 24mm. This uncommon width is characteristic of this particular model and reflects the harmonic proportions of the 42mm case. To verify strap compatibility, measure the internal distance between the lug pins with a calliper.

Strap selection depends on intended use: dark brown or black alligator for technical elegance; vegetable-tanned calf for those desiring patina development; grey or blue aviation NATO for authenticity; technical rubber for water sports and professional environments. The 24mm width enhances case proportions across any pairing.

Locate the two lug pins (small protrusions on both sides of the case). Using a spring bar tool or small flathead screwdriver, depress each pin toward the centre of the lug to release it. Remove the old strap and insert the new one, ensuring the holes align. Confirm both pins seat fully before wearing the watch.

Yes, provided the strap is engineered for 24mm lug width. Quality artisanal straps guarantee full compatibility when manufactured to technical specification. Always verify with the seller that the width is confirmed as 24mm: this width is not universal, so measurement error represents the primary risk.

A quality leather strap (alligator, vegetable-tanned calf) lasts 5–7 years with regular use and minimal maintenance: annual cleaning with gentle detergent, protection from prolonged sun exposure, storage in dry conditions. Factors such as humidity, frequent perspiration, and daily wear may reduce lifespan; alternating straps significantly extends the life of each piece.
