Strap for Oris TT1 01 635 7518 4464

The lug width of the Oris TT1 01 635 7518 4464 is 24mm. This measurement represents the distance between the spring bars that connect the strap to the case. You can verify it by removing the original strap and measuring with a calliper the internal distance between the attachments, or by positioning a ruler parallel to the case lugs without disassembly.

The ideal strap depends on your intended use. For formal contexts, an alligator strap from vegetable tanning in medium tobacco brown represents the most versatile and refined choice. For sports use, FKM rubber straps maintain elasticity and resistance to external agents. Alternatively, superior quality calf leather offers a balance between formality and daily comfort. Military canvas NATO straps emphasise the piece's aeronautical heritage.

Changing the strap requires the use of a spring bar tool or a small lever. Position the tool under the bar towards the inside of the case and apply gentle pressure to release it. Repeat on the other side. The original strap releases easily. Insert the new strap by aligning the side holes with the bars and press until you feel a click. Verify that the bars are fully inserted.

Any strap equipped with 24mm lugs is compatible. Milano Straps offers a dedicated collection of straps in alligator leather, calf, shell cordovan, FKM rubber and NATO canvas, specifically dimensioned for this size. Each strap is handcrafted and available in multiple finishes and colours. Compatibility is guaranteed by universal spring bars.

The lifespan of a leather strap depends on the material and usage. A superior quality alligator or shell cordovan resists 5 to 8 years with moderate daily use, developing a patina that increases the aesthetic value of the piece. Traditional calf leather has an average lifespan of 3-5 years. Exposure to excessive moisture, salty sweat and thermal variations accelerates wear. Regular maintenance with specialised hydrating creams significantly extends useful life.
