Strap for OT-2

The Dietrich OT OTCAO2 features a lug width of 20mm. This measurement is specifically calibrated to the proportions of the 46mm case to maintain the aesthetic and functional balance of the model. To verify compatibility with your strap, measure the outer distance between the attachment pins: the value must correspond exactly to 20mm.

The OTCAO2 expresses itself magnificently with alligator or vegetable-tanned leather, which enhance the contemporary elegance of the stainless steel case. High-quality NATO straps represent a versatile option for daily wear, whilst fluoroelastomer rubber straps impart a sportier dimension while preserving the model's nonconformist identity. The choice depends on your intended use and the narrative you wish to construct with the timepiece.

The strap is removed by acting on the lateral pins (lugs) that traverse the bracelet attachment points. Use a dedicated pin pusher or small flat tool to gently press the pins from one side, facilitating strap extraction. Once removed, insert the new strap by aligning the holes with the pins and press until fully seated. Ensure the strap is perfectly positioned on both sides of the case.

Yes, any strap with a 20mm lug width is compatible with the Dietrich OT OTCAO2. Artisanal straps of quality—crafted in alligator, leather, NATO, or rubber—fit perfectly onto the case pins. We recommend selecting straps from specialised suppliers to ensure construction quality and aesthetic finish consistent with the watch's calibre.

The lifespan of a leather strap depends on material quality, usage frequency, and environmental conditions. An alligator or vegetable-tanned leather strap, with proper maintenance, can last between 3 and 5 years under regular use. Prolonged exposure to moisture and sunlight accelerates ageing. Periodic maintenance—gentle cleaning and, if necessary, conditioning—significantly extends the strap's functional life.
