What time is it? Watches and horology

Haha! Case and lens are perfectly round. Not black on black, just lighting. The numerals on the 39mm are solid white gold so you're looking at light reflecting off edges not faces.

I like both for different reasons. The case on the 39mm has more curvature at the tip of the lugs, which isn't obvious from the pics (because it's wider) but a nice touch. Also the bracelet on the 39mm is streets ahead of the 36mm.

But the 36mm has a simple robustness about it, even if it does wear slightly small on my ape wrists it doesn't bother me. They're both lovely - as they say in Thailand "Same, same! But different".
