Crocodile Strap for the Small Cartier Tank Must
Share
The small Tank Must is a hard watch to buy a strap for, and the reason is arithmetic. Almost every aftermarket crocodile strap is cut for a men's case, which means the tail is too wide, too long and too thick for a small Tank the moment it comes out of the packet. An order from Scotland set the numbers directly instead: 75/115mm, a flat profile, and a tail finished at 14mm so the owner's existing buckle would carry over.

Why these choices

Scale size is the thing people underestimate on a small case. Crocodile and alligator are the same hide family and both soften and take a hand-rubbed patina, but a strap cut from the wrong part of the belly puts three enormous scales across a 14mm tail and the watch ends up wearing the strap. Cutting a small Tank strap means selecting a run of tiles that stay in proportion to the case, which is a sourcing decision before it is a leatherwork one.
The flat profile does the same job. Padding lifts a strap off the wrist and adds height at the lug end; on a slim rectangular dress watch that reads as bulk in exactly the wrong place. Building it flat, with side stitching in a matching thread rather than a contrast, keeps the strap reading as part of the watch instead of an accessory bolted to it.
Finishing at 14mm was the requirement everything else worked around. When a customer is reusing hardware, the tail has to arrive at the stated width exactly — a millimeter of slop and the buckle rattles. The quick-release bars were the customer's own addition, and they make sense on a watch likely to rotate between a few straps.

★★★★★
“The OEM strap was short and stiff. This replacement is wonderful — nice quality, supple, longer, and made to spec as I used the original buckle. Perfect fit. Will be buying more.”

Common questions
How do I order a crocodile strap for the small Cartier Tank Must?
Give us the width your buckle needs and the two lengths you want, short side and long side. If you are not sure of the lengths, send your wrist measurement and we will work back from it.
Will the strap fit under the Cartier deployant clasp?
Tell us in the order notes if you are using one. A folding clasp needs the tail sized to the clasp rather than to a pin buckle, so we cut it differently.
Straps are made to order — allow two to three weeks to delivery. Start with the brown crocodile strap, browse the full crocodile leather range or the Cartier strap collection, or see the rest of what we build to measure in custom leather watch straps.
