Professionally tested & guaranteed solid 18K Gold. Stamped 750 and clasp functions as intended. The genuine leather band is worn and should be replaced soon. The watch would benefit from cleaning and polishing. It keeps accurate time and everything functions as it should. I had it inspected my a master watchmaker to make sure it didn't need any repairs so you can have confidence in buying a fine timepiece which will last a lifetime and never need a battery since it runs off the movement of your wrist but may need to be worn for a little while if it's been sitting for some time to get started again. Please refer to pictures for a better of condition and measurements. If you have any questions, or desire more photos, information or videos please feel free to message me. Peace of mind 30 day money back guaranteed if you are not 100% satisfied with your purchase.
