Strap for Carrera Calibre Heuer 02 43 Carbon / Skeleton / Rubber

The lug width of the CBG2017.FT6143 is 20 mm, measured from inner lug to inner lug. This dimension allows the use of a broad range of compatible artisanal straps, from alligator models to sporty NATO options, whilst maintaining optimal proportions relative to the 43 mm case.

The choice depends on intended use and personal preference. Alligator leather with vegetable tanning offers sophistication and natural patina development over time. Smooth calf guarantees understated elegance and ease of maintenance. For aquatic environments or intensive sport, rubber or NATO straps ensure waterproofing and rapid drying, without functional compromise.

Use a spring bar tool. Insert the flat end into the lateral gaps beneath the lug, pressing inward to compress the spiral spring that holds the pin. Once compressed, the pin will slide from its seat. Repeat on the second terminal, then insert the pins of the new strap and release the tool. The operation takes minutes if executed carefully.

Yes, any 20 mm strap with standard lug seat depth—approximately 1.5 mm—is compatible. Milano Straps offers a broad selection of artisanal straps in alligator, calf, shell cordovan and rubber, all customisable in length, initials and stitch colour. All undergo quality inspection before dispatch.

Lifespan depends on tanning and treatment. A calf or alligator strap with vegetable tanning resists 3–5 years in regular use, developing natural patina over time. Shell cordovan, more durable, can exceed 7 years. Critical factors are: water exposure, humidity, direct sunlight and frequency of use. Regular maintenance—drying after water contact, seasonal conditioning—significantly extends lifespan.
