My son-in-law asked me to sell for him. I need help establishing a value and I am open to offers as well. Professional 2000 (200 meters) WK1110-0 Serial number (I guess) PC7xxx It was purchased new, worn for 3 years, then locked away in controlled condition vault. Battery was replaced this week. I have the booklets that came with it, including warranty/registration card. No scratches. I have a photo of the back of the watch, but not sure should post with the serial number. Here are other photos. Thanks for your help in placing a value...or even more thanks for making a fair offer and buying!
