Nice looking watch, can’t help ya on the brand though but it seems like some others in here have. My condolences for the loss of your grandfather.

You should post a pic here of his collection, I always love seeing the older generations taste in watches and what their collections look like. My grandfather left me a few watches and he had a Seiko for everyday use and some really nice pieces for special occasions. If you do end up making a post of his collection please comment here and let me know, I’d love to see it!

Hope you’re well and have a wonderful day.
