Strap Guide: Cartier Tank Must Blue WSTA0055

Strap Guide: Cartier Tank Must Blue WSTA0055


Strap Guide written by @onceuponatimepieceThank you Samuel!


When Cartier revealed the new colorful Tank Must collection, I knew I had to get one. These minimalist pieces are similar to the Must de Cartier watches from the 80s that I simply adore. The smaller case and the minimal dial make this watch elegant and timeless. However, after purchasing this blue Tank, I wanted to see what it would look like with different straps. To my amazement, this piece is quite versatile, but before I dive into the various straps that I chose, let’s go with the basic information. The case size is 33.7 mm x 25.5 mm, and the lug width is 19mm. For reference, my wrist is 16.5cm/6.5,” and all straps are 19mm lug width. The OEM buckle can be fitted to these straps. The dial is a beautiful darker blue with a lacquer finish. And because it is a Tank, it has the signature cabochon crown. 

Navy Chevre Slim Strap

For the Tank, this strap is a Must (pun intended). This strap stands out with its luxurious texture and grain. The leather comes from the Alran tannery, and it’s often used in small leather goods. The strap is very smooth and soft, and it has a beautiful pebbled texture. This grain pattern is more delicate than Epsom, and you can really feel the difference. You can dress up a watch with this strap, and that’s why I always choose it when I’m wearing a suit.

Pastel Blue Nubuck Slim

This combination screams summer nights in the French Riviera. So pick up a white linen shirt, linen shorts and put this strap on your Tank, and you are good to go! Maybe grab a Negroni on the way. Don’t feel like traveling? No worries, this Nubuk strap looks great with jeans and a T-shirt. This Nubuck strap is silky smooth, and the pastel color gives the dark blue dial a nice contrast. Also, did you know that nubuck is more durable than suede? So you don’t have to worry about the leather getting tarnished that easily. Finally, this feels unbelievably comfortable on the wrist, which makes this a great everyday strap.

Matte Black Alligator Signature Strap

An alligator strap is an excellent option to class up your timepiece. You can play around with the different hues and finishes. Here, I went with the matte black finish. Call me crazy, but this black alligator strap goes perfectly with a tuxedo or a black hoodie!

Light Grey Epsom Slim strap

This Grey Epsom strap is probably my favorite option from these. I love the delicate texture of the Epsom leather, and the shade of grey complements the blue dial nicely. This particular leather comes from the Tanneries Du Puy in France, and they are well known for their high-quality leathers. You can easily dress up this strap, but it works perfectly with comfortable knitwear like the one I am wearing here. 

Dark Brown Saffiano Stitchless

The saffiano leather is known for its signature cross-hatch grain. The pattern is quite subtle yet very recognizable. You don’t have to worry about this strap because it is very scratch and water-resistant. The Saffiano strap is a great “all-rounder,” and this particular dark brown option transforms the blue Tank into a casual everyday timepiece. Combine it with a green jacket, and you have a solid look.
