Vintage marcasite 925 silver watch bracelet

Vintage wind up watch. Watch does work but must be wound up ,it's not quartz The watch face is opalescent. I could not find any marks for watch brand. The watch is stamped 925. My wife lives opals. My wife doesn't remember if it was bought for her or given to her from her mother. She remembers saying to her mother without numbers it was hard for her to tell time 🤣 🤣 🤣. It's been in her jewlery box over 40 years. Beautiful 925 silver marcasite bracelet makes a beautiful piece of timeless jewlery. please look at pictures this is vintage and pre-owned. The chain attached to the closure is missing.
