So my CW Slimline Square just got delivered. Of course it's necessary to try it on immediately. The strap is, unsurprisingly, too large. That's not overly surprising or disappointing. So it's time to check the spare straps. We're talking a fairly formal piece...polished finishes, white dial, minimal printing. This has the old dial printing, which IMO is preferable.
So...oh, hey, look. The gray suede, that was the spare strap for my emerald green Veli that came in last week. I didn't check...but the other strap, *on* the Veli, was just a bit too long. Position it relative to the CW...yep, it's notably shorter. (Measuring later...looks like the CW is around 125/85 vs. 115/80.)
But the Veli's 38mm round; the CW is 37mm square...with very short lugs. The lug to lug is less than the case size difference alone would suggest.
So...pop off the CW. Oh, nice, it has quick release spring bars. Slip in a couple 20mm's...pop them in. Voila! There's more tongue than one might like; the buckle's a tad forward of wrist center...but the fit's perfect.
Note to self: a square watch case probably wears 2 to 4 mm smaller than a round of the 'same size'. With, of course, much more dial.
