This is an uncommon vintage 1975 18k. solid gold Rolex Cellini. This is likely the largest of the vintage Cellini models, measuring 24.5x41mm.and elegantly thin at 6.5mm. including the crystal. The manual winding original Rolex movement was just cleaned and is accurate. These Rolex manual winding movements are simple to maintain, due to the lack of automatic (extra parts). The original gold dial is extremely clean. The 18k. solid gold case has been amazingly preserved, with the serial number visible and deep 18k. hallmark. The original Rolex winding crown and sapphire crystal are present. This vintage Rolex watch SPREADS across the wrist. I’ve owned 3 of these over the decades-this example is the cleanest I’ve found. You will love it.
