Up for sale is my pilot chronograph. This watch is not a home build. I purchased this watch with sterile dials The watch might have two or three hours of first time at the most so the watch is in your mint condition. Here are the specs : quartz movement Miyota 7S21. Sapphire crystal. Water resistant to 50 m. Case diameter is 40 mm and is 11.5 mm thick. The lug width is 20 mm. No trades. Plenty of references.
