I was going through my watch parts and with the Oyster links I noticed this part. Seeing as it 20 years since this was put away I have no idea where it goes or if it is even a Rolex part ! It was with extra links for a 93150 L2 code bracelet. I am thinking it is from the previous bracelet (1971) which was destroyed in an accident, (don't ask me !) Can the bracelet gurus give me a clue ?
Yup, it was an insurance job this part was in my watch box . The bracelet was replaced with a 93150 in 87. Sad story .
