I just received this watch as a gift from my grandfather, who got it from his grandfather. it is an amazing piece, and even started right back to life after sitting for probably 30+ years. However, I can’t seem to identify it. It has a very unique case shape which I cannot find online. I have not yet been able to open it up, but I believe it is a calibre 59 movement and I know for a fact it is 18000bph. It‘s about 32mm and the dial reads “Tudor precision” and “shock resistant” Any help in identifying it or any knowledge about it whatsoever would be appreciated. I will make another post or update this post once I get better pictures after polishing the crystal.
