It’s the weekend so today’s watch is a hand winder 🙂 The Diamond Flake was Japan’s thinnest watch when it was launched in 1962. The 25 or 31 jewels 0700 movement was a mere 2.75mm deep, beating the Seiko Gold Feather by just 0.2mm. My example is from September 1963 – I haven’t had chance to do a fresh photo today, so this is an old one:

There’s more on this and the very nice movement here: https://sweep-hand.org/2013/05/15/this-weeks-featured-watch-51-the-diamond-flake/
As the ‘lock-down’ is eased and life gets busier, I’ll be doing fewer ‘Today’s Watch’ posts – still got more to show you though 🙂
