The lugs are thick and well-defined. The caseback is well-preserved with just a couple minor hairlines to the brushed finish. The backs of the lugs show signs of prior strap removal. The brand, serial number, and hallmark engravings remain sharp and legible. **Dial, Hands, & Crystal:** The cream dial and polished hands are in pristine condition with no notable imperfections. The hands are original tritium-filled units and match the hour markers. Both glow briefly glow when exposed to UV light. The sapphire crystal is squeaky clean and scratch-free. **Bracelet/Strap:** The Blancpain navy alligator strap is in fantastic condition with minimal signs of use. The sides show very tiny cracking in a couple spots and the leather backing shows faint creasing, but nothing major in either case. The condition of the Blancpain-signed platinum buckle is consistent with the rest of the case. The brand and hallmark engravings remain crisp and detailed. **PERFORMANCE** **Timing:** The watch has been measured with a timegrapher at six different positions. The rate, amplitude, and beat error are within acceptable ranges. While resting face up, the rate is -3s/d. **Functions:** All functions including the crown winding, time setting, and date changing are working as expected. **Service History:** Unknown. **WHAT'S INCLUDED** * Blancpain Ultra-Thin Platinum on a navy alligator strap.
