1680: This is an excellent example of an early Red Sub. With a serial number starting with 2.0, this is from the very first batch of Red Subs- like a patent pending SD!
Nice thick lugs and overall excellent case. Fully legible numbers between the lugs. No major dings or scratches.
Original "Long F" dial in excellent condition, original tritium on dial, hands, and pearl. The tritium on the hands and pearl are slightly darker in color than dial, but all 100% original.
Comes on a solid link 91350 bracelet with 593 end pieces. Bracelet has light to moderate stretch.
