This showed up on the bay today. It’s a lady’s Ricoh “Humming”, manual wind, two-hander with date. I expected to see a hummingbird pictured somewhere in the dial, but no. And, the four long cross hair lines are reminiscent of some Accutron dials I’ve seen. The movement is marked Ricoh, but not the dial.
This holds no real interest for me - but it’s a bit curious.
