My Divine Size Comparison guide: Rectangular vs Circular vs Tourneau

When I compare the size between a rectangular watch and a circular watch. I use the area (mm square) to compare their size. It works really well.

For example, if a rectangular watch is 25mm x 32mm. Then its area is 800 mm square.

Image

If a circular watch is 32mm in diameter, then the radius is 16mm. The area is 804mm. Which is slightly bigger than the rectangular watch

Image

But if the watch is tourneau shape. Then you’ll literally have to go back to middle school:

Image

See the above example Tourneau. You have to calculate the area of the rectangle and then minus the 4 missing triangles in the corner

No one said there would be math on this site!

Lots of math and big words just to say:

I’ve always been told size isn’t important it’s what you do with it! 🤘

I had to have tutoring for geometry and never did get the hang of it. So I just eyeball it. If it looks bigger it is bigger. YMMV.

Were I to actually be looking into buying a watch, I'd just do a physical mockup with cardboard or something. However, the geometrical area formula is useful for showing how awful larger watches are.

I'll do the math off the sheet but trust me, bro.

Oh but it's only a few millimeters! NO! Take the gap from a medium-large watch (36mm) to a LARGE watch (40mm). People will think 4mm is small but the area has increased by over a third! And it gets worse when we get into the truly vulgar sizes.

Pie are squared? I thought pies were round?

You are not wrong about large watches, but the increase isn't by over a third 😉 it's 23.5% which is also supported by the excel you got there.

You got me. I was looking at the area for 35mm and lazily approximating in my head. Actually, let me go back and do the linear size percent increase increments vs. the area increase by percentage...

A barrel-ish shape is called tonneau, not tourneau.
