Square Watches UK 2026 Why Round Is No Longer the Only Option

The round watch has dominated wrists for a century.

It didn't have to. The wristwatch arrived in the early 1900s at a moment when rectangular and square cases were just as common. The round case won out for practical reasons easier to manufacture at scale, more comfortable on the wrist, simpler to read at a glance. Those reasons were real in 1920. They're less compelling in 2026.

The square watch is back. Not as a novelty or a throwback as the dominant design direction of the decade. Here's why.

Why square is having its moment

Every major watch house with credibility in 2026 is leading with square and rectangular cases. Cartier's Tank is the most copied case shape in watchmaking history. Richard Mille's rectangular cases are the most expensive watches in the world. AP's Royal Oak technically octagonal but closer to square than round in its visual impact defined sports luxury watchmaking for fifty years.

At the independent level, the square case offers something the round case doesn't: genuine visual distinction. On a wrist full of round watches, a square case stops people. It reads as a deliberate choice rather than a default. That deliberateness is increasingly what buyers are looking for.

The practical case for square has also strengthened. Modern manufacturing has removed the production difficulty. Modern watch straps and bracelets are designed for square cases with the same care as round ones. And legibility the original argument for round is not actually better on a round dial. The Cartier Tank reads perfectly clearly. So does the 365.

What to look for in a square watch

Proportion. The case height-to-width ratio defines the character of a square watch more than almost any other specification. A wide, shallow square reads as architectural and modern. A taller, narrower rectangle reads as classic and dress-oriented. The 365 series sits at the architectural modern end a broadly proportioned square case that reads confidently on the wrist without mimicking the Tank's more elongated proportions.

Dial complexity. Square dials give more visual options than round ones. The corners allow for design choices that circular constraints prevent. An open skeleton dial in a square case like the 365 Gold Skeleton uses the architecture of the case to frame the movement rather than simply centering it.

Case material. The same rules apply as for any watch. Grade 316L stainless steel holds the finish under daily wear. Sapphire crystal resists the scratching that a heavily-worn everyday square watch would otherwise accumulate quickly.

The Tomell London 365 collection square watches from £195

365 Gold Skeleton  £345

The flagship. A square gold case with an open skeleton dial showing the self-winding Miyota automatic movement beneath sapphire crystal. No battery. The watch that generates the most attention in the 365 range. The open dial and the square case are two design choices that both signal deliberate intent together they produce a watch that reads as significantly more expensive than its price.

365 Gold Automatic  £345

The clean automatic. Same square gold case as the Skeleton, stardust dial instead of open skeleton. For those who want the square architecture and the automatic movement without the exposed dial. The stardust finish catches light in the same shifting way as the frosted cases.

365 Silver Automatic £345

The silver version. Square silver case, stardust dial, self-winding automatic movement. The most versatile of the automatic 365 pieces the silver tone works across warm and cool outfits in a way gold doesn't.

365 Green Ruby £195

The entry point. Square gold case, deep emerald green dial, Japanese quartz, sapphire crystal. Under £200. The design boldness of the 365 range without the automatic movement price. The green dial is the colour of 2026 watch design.

365 Purple Ocean £195

Square silver case, deep purple dial, Japanese quartz, sapphire crystal. Under £200. Purple is the dial colour that most watch brands won't touch which is exactly why it stands out on every wrist it's worn on.

365 Rose Titan £195

Square rose gold case, black dial, Japanese quartz, sapphire crystal. The combination that produces the strongest contrast in the 365 range warm rose gold against a deep black face.

Square vs round which should you choose?

The honest answer: if you already own round watches, a square watch gives you something genuinely different. Not better or worse different in character, different in the impression it makes, different in the conversations it starts.

If this is your first watch, a round case is the safer choice for maximum versatility. If this is your second or third watch and you want to expand beyond the standard, the 365 is where to go.
