Strap for Carrera Connected Modular 45 Titanium / Orange Aluminum / Orange Rubber

The lug width of the SBF8A8016.11FT6081 is 20mm. This measurement represents the internal distance between the two attachment points where the strap anchors to the case. It is important not to confuse this measurement with the case diameter, which is 45mm. To verify compatibility of an aftermarket strap, always measure the space between the lugs with a digital calliper: it should read between 19.8 and 20.2mm to ensure a secure fit without lateral play.

The best strap depends on intended use. For elegance and durability, alligator leather is the optimal choice: its natural grain contrasts elegantly with the brushed titanium case. For versatility and visible ageing over time, nappа calf leather in brown or black shades allows a personal patina to develop. If you seek certified water resistance without sacrificing practicality, vulcanised FKM rubber straps maintain aquatic resistance. NATO straps in cordura enable rapid changes, ideal if you use the Connected Watch across multiple sports.

Strap replacement on the Connected Watch SBF8A8016.11FT6081 occurs via standard 20mm spring bars. Proceed as follows: 1) Use a dedicated tool (spring bar tool) to gently compress the spring bar on one side. 2) Remove the small bar from its seat in the lateral holes of the case. 3) Repeat the operation on the opposite side. 4) Insert the new strap, aligning the holes with the lug seats. 5) Reinsert the spring bar whilst compressing it slightly. We recommend having a professional watchmaker perform this operation if you lack experience, to prevent case damage.

All straps fitted with 20mm lugs are compatible with the SBF8A8016.11FT6081. This includes leather straps (alligator, calf, crocodile), vulcanised rubber, FKM, butadiene rubber, NATO nylon and cordura. It is essential to verify that the attachment is realised via standard 20mm spring bars. We advise against straps with proprietary systems (special deployant clasps) incompatible with standard spring bars, as these would require modifications that could compromise the structural integrity of the titanium case.

The lifespan of a leather strap depends on tanning method, frequency of use and exposure to external agents. Alligator leather, if treated with impregnant (cream leathercare), maintains structural integrity for 5–8 years of daily wear. Nappа calf typically lasts 3–5 years, developing visible patina within six months. On a Connected Watch, frequent use in aquatic environments (for which this smartwatch is designed) reduces overall lifespan: repeated exposure to salt water and chlorine damages fibres even in premium leathers. To extend service life, always dry the strap completely after water contact and apply protective treatments every six months. FKM rubber straps offer greater durability (7–10 years) but lose elasticity more readily.
