Cartier's Tank Must, in its large size, is a steel rectangle 25.5 mm wide and 33.7 mm long, with a rail down each side, a silvered dial with black Roman numerals and a railway minute track, blued steel sword hands and a blue cabochon on the crown. It runs on what Cartier calls High Autonomy quartz. In the US it lists at $3,900 on a black calfskin strap.
That's a lot for a quartz watch, and the shape is easy to find for less. We went through what's on sale in the US today and kept five watches like the Cartier Tank, from $575 to $1,650, each with the thing it gets wrong. Prices are US list prices from the brands' own sites, checked on 24 October 2026. The photos are to scale, so if a watch looks narrower here, it is.
One of the five, the Söner Tank Royal, is marked as a homage, the watch world's word for a watch from a smaller brand that follows a famous design on purpose, under its own name. A warning about two of them: Hamilton's US site shows the Ardmore as "Available soon", and the Tank Royal is on pre-order until Söner launches it.
This is the watch every pick is measured against, the Tank Must in its large size, reference WSTA0136, on six points:
Cartier's page describes the crystal only as "square-shaped glass", so we can't tell you what it's made of. Every pick runs on quartz too, so none of them asks you to give up a mechanical movement. None of them has the blue cabochon, and none matches the Tank's size exactly, though the Söner Tank Royal comes close. Nothing we found between $1,650 and the Tank's own $3,900 looked close enough to make the list.
| Watch | US list price | Case (width x length) | Water resistance | Movement |
|---|---|---|---|---|
| Hamilton Ardmore Small | $575 | 19 x 27 mm | 30 m | Quartz (980.163) |
| Söner Nostalgia Agustus | $765 | 28 x 40 mm | 50 m | Quartz (ETA 901.001) |
| Söner Tank Royal Steel (homage) | $920 | 24 x 34 mm | 50 m | Quartz (ETA 901.001) |
| Raymond Weil Toccata | $1,175 | 29 x 37 mm | 50 m | Quartz |
| Longines DolceVita | $1,650 | 23.3 x 37 mm | 30 m | Quartz (L176.2) |
| Cartier Tank Must, large, for comparison | $3,900 | 25.5 x 33.7 mm | 30 m | Quartz |
The Ardmore is the cheapest way into the Tank's shape, though not its dial. It's a curved steel rectangle, 19 mm wide, 27 mm long and 6.9 mm thick, on a black leather strap, with a silver sunray dial, a few black Roman numerals with batons between them, silver hands and a small seconds dial at 6. Hamilton files it as a women's watch. Inside is the quartz calibre 980.163, under a mineral crystal, and it's water resistant to 30 metres, the same as the Tank.
What you give up is most of the Tank's dial. There's no railway minute track, the hands are silver, not blue, and the crown has no cabochon. The case is 6.5 mm narrower than the Tank's, as the photo shows, and it's the only pick with a mineral crystal, where the rest have sapphire. Hamilton doesn't publish the battery life. It costs $575, about a seventh of the Tank's price, but Hamilton's US site lists it as "Available soon", so you can't order one there today.
Under $1,000, the Agustus has more of the Tank's dial than anything else, which is why we call it best value. It's Söner's own design with Tank cues, not a homage: a silver dial with black Roman numerals, a railway minute track and blued hands, in a polished steel case on a black alligator-pattern leather strap. The hardened stainless steel case is 28 mm wide, 40 mm long and 7 mm thick, under a sapphire crystal with an anti-reflective coating, and it's water resistant to 50 metres. Inside is a Swiss ETA 901.001 quartz movement with an 11-year battery.
What you give up is the Tank's proportions and its plain centre. The case is 2.5 mm wider and 6.3 mm longer than the Tank's, and its sides are stepped flanks, not true side rails. The middle of the dial has a pattern the Tank's doesn't, and the crown is plain steel, with no cabochon. It costs $765, a fifth of the Tank's price.
If the shape is what you're after, this is the closest watch here at any price. It follows the Tank on purpose: a polished steel case with side rails, 24 x 34 mm against the Tank's 25.5 x 33.7, with black Roman numerals and a railway track on the dial and a black alligator-pattern strap. On paper it matches the Agustus: hardened stainless steel, a sapphire crystal with an anti-reflective coating, 50 metres of water resistance and an ETA 901.001 quartz movement with an 11-year battery. Söner doesn't publish the case's thickness.
What you give up is the Tank's colours and, for now, the watch itself. It's on pre-order: Söner says the official launch is November to December 2026, so it isn't shipping yet. The dial is white, not silvered, the hands are black batons instead of blued swords, and the crown is hidden, so there's no blue cabochon. It costs $920, about a quarter of the Tank's price.
If 25.5 mm sounds small to you, the Toccata is the bigger take on the Tank's dial: 29 mm wide and 37 mm long, with black Roman numerals and a railway-track frame on a white dial. It's thinner than the Tank, at 6.4 mm, in a polished steel case under a sapphire crystal, on a black calf strap with an alligator motif, and it's water resistant to 50 metres.
What you give up starts with the case, which has no side rails. The hands are steel leaves, where the Tank's are blued swords, and there's a date at 3 that the Tank doesn't have. Raymond Weil says only that the movement is quartz, without naming the calibre or publishing the battery life. It costs $1,175, about a third of the Tank's price.
We call this one best built, for its movement and its dial. The quartz calibre L176.2 runs on a Renata 379 battery and has an end-of-life indicator, so it warns you before the battery runs out. The dial is silver flinqué, with painted Roman numerals that look dark blue in the photo, an inner railway frame, blued steel hands like the Tank's and a small seconds dial at 6. The polished stainless steel case is 23.3 mm wide, 37 mm long and 7.2 mm thick, under a sapphire crystal, on a black alligator strap, and it's water resistant to 30 metres. Longines lists it under women's watches.
What you give up: the numerals look blue where the Tank's are black, there's a small seconds dial the Tank doesn't have, and the case is 2.2 mm narrower and 3.3 mm longer than the Tank's. Longines doesn't publish the battery life. It costs $1,650, about two fifths of the Tank's price, the most of any pick here.
