Strap for Carrera Calibre Heuer 02 42 Stainless Steel / Japan

The TAG Heuer Carrera CBN2019.BA0642 features a lug width of 20 millimetres. This dimension accommodates wide, structured straps specifically sized to the tonneau profile of the case. To verify compatibility, simply measure the distance between the inner edges of the spring bar lugs on the caseback.

Black alligator with medium grain paired with a stainless steel deployante represents the ideal choice stylistically, reflecting the racing heritage of the Carrera. For a more sport-oriented approach, FKM rubber in black guarantees grip and rapid drying. Italian vegetable-tanned calf offers a versatile solution with warm patina development over time. Ballistic nylon NATO straps in grey represent a casual-elegant alternative.

The procedure requires a spring bar tool: insert the tool tip gently under the spring bar, compressing it slightly to free the pin. Once extracted, disconnect the old strap and position the new one, reinserting the spring bar with care. The operation must be performed on a soft surface to prevent case scratches. If uncertain, consult an authorised jeweller or service centre.

Yes, any strap with a 20-millimetre lug width is compatible with the CBN2019.BA0642. Aftermarket straps, provided they are crafted from quality materials (alligator, shell cordovan, vegetable-tanned calf, FKM rubber), maintain the Carrera's stylistic proportions and do not compromise the case. Milano Straps offers a selection of 20mm straps specifically tested with Carrera family models.

Durability depends on frequency of wear, leather type and storage conditions. Quality alligator, worn daily, withstands 3–5 years before showing wear signs. Vegetable-tanned calf develops patina within 18–24 months, with overall lifespan of 4–7 years. Exposure to moisture, perspiration and direct sunlight accelerates ageing. Rotating with alternative straps (rubber, NATO) significantly extends the lifespan of each leather strap.
