Before the Tank Must took over, there was the Tank Solo XL W5200028 — the automatic Tank that introduced a whole generation to Cartier. Produced for nearly a decade, it paired the classic 31 x 41 mm rectangular case with a silvered opaline dial, blued sword hands, a date at 6 o'clock, and a steel bracelet. Thousands of them are on wrists and circulating on the pre-owned market today, and for owners, a strap swap is the single easiest way to give this discontinued classic a second life.
This guide explains the correct strap size for the W5200028 — including a sizing detail many owners get wrong — and the most popular Helvetus strap options for this model.
Cartier Tank Solo XL W5200028 Strap Size and Fit
For the Cartier Tank Solo XL W5200028:
- Model: Tank Solo XL, automatic
- Case size: 31 mm x 40.85 mm, rectangular
- Attachment: standard spring bars — no QuickSwitch on this generation
- Strap width at the case: 23 mm
This means the watch requires a 23mm strap. When ordering, simply select the 23mm option on the product page.
Worth knowing: you will sometimes see 22 mm listed for this watch, and owners who try a 22 mm strap end up with a visible gap at the lugs. The case measures 23 mm between the lugs, so 23 mm is the correct choice for a flush, secure fit. Helvetus Tank straps come with spring bars included and are compatible with the original Cartier folding clasp.
As with every Tank, proportions matter too. The slim rectangular case needs a strap with clean, straight lines — Helvetus Tank straps are cut specifically to follow the case, so nothing sits awkwardly against those signature brancards.
From Bracelet Watch to Strap Watch in Minutes
The Tank has been around since 1917, but the Solo era made it attainable — and the XL automatic was its flagship. The W5200028 came on a steel bracelet, which is exactly why a strap changes it so dramatically. On leather, the same watch suddenly looks the way Louis Cartier drew it: a rectangle of polished steel framed by stitched leather.
There is a practical side as well. Rotating to a strap keeps the original bracelet free of scratches, which protects the value of a discontinued reference. Many Solo XL owners wear leather through the week and save the untouched bracelet for the box.

Below are the most popular choices among owners of this reference, matched to its silver dial, blued hands, and polished steel case.
Black Leather Strap
Black leather is the definitive Tank pairing and the most popular choice for the Solo XL. It turns the bracelet watch into the classic dress Tank instantly — sharp against the silver dial, at home with everything from a suit to a sweater. Black Leather Strap for Cartier Tank Solo
Black Crocodile Strap
For maximum formality, black crocodile is the strap this design was born on. The scale texture adds richness that smooth leather can't, and it gives the W5200028 the presence of Tanks costing several times more. Black Crocodile Strap for Cartier Tank Solo
Brown Crocodile Strap
Brown crocodile leans vintage in the best way. Against the silvered opaline dial it gives the Solo XL a warm, old-money character — a favorite among owners who wear the watch daily and want it to feel a little softer than black. Brown Crocodile Strap for Cartier Tank Solo
Red Leather Strap
Red is Cartier's own color, and on a silver-dial Tank it is a brilliant statement. It stays elegant rather than loud — think of it as the strap equivalent of the red Cartier box — and it photographs beautifully. Red Leather Strap for Cartier Tank Solo
Beyond these four, the collection includes further colors and finishes, all cut to the same Tank proportions.
Final Thoughts
The W5200028 may be out of production, but on the wrist it has lost nothing — the proportions, the dial, the thinness all still work. Put it on the right 23mm strap and it stands next to any Tank Cartier makes today.
