Got this at a Spanish car boot on a recent holiday, the old guy with the stall had loads of old watches, some I'd never heard of 'Royal' was one, the others I forget but there were also others I did Ingersol, Record all the usual suspects of all ages including a few'trench' watches interestingly he had several old Citizens from the 1970's all identical that could have been NOS.
Sadly I wasn't expecting much in the way of watches to be there so this was all I could afford as I only took a 10 Euro note!(not next time)
A seiko 6106-9050 Automatic in full working order though with a replacement strap and in need of a new crystal.
I think he was an old watchmaker or disposing of a friends collection but they were all in vgc, all clean and working.
