Flatlink Bracelets
Note: wonky non-functional 7912 stretch links have been replaced - see my reply below.


1. 7912 flatlink bracelet w/ #7 endlinks
Bracelet is in decent, unpolished condition. Comes with 10 stretch links, all of which are fully functional (I recently replaced the springs on the four that were faulty previously - see photo in my reply below). One of the non-functional stretch links has some rust on the front (edit: most of this has no been removed - see photos below). Length is a little under 15cm from springbar to springbar (unstretched). Bracelet clasp is dated to 4/62 (Q4 1962).
Price: $1300 (reduced from $1400) without endlinks, +$200 with the original #7 endlinks which fit Seamasters/Rancheros of the era.

2. 1175 flatlink bracelet w/ #48 endlinks
Bracelet is in nice, unpolished condition. One link has some corrosion on it. Comes with two spare links - one of which needs a new spring bar. Length is 14.5cm from springbar to springbar + ~1cm from the two spare links. Bracelet clasp is dated to 10/70 (October 1970).
Price: $550 (reduced from $650) bracelet only, +$200 with the original 19mm #48 endlinks [endlinks now sold, bracelet still available].


3. Spare 18mm #4 endlinks
3a. [top] One double notch endlink in nice condition. $100 [sold]
3b. [middle] One single notch endlink in nice, seemingly unpolished condition (clear brushing on the inner link area). $110.
3c. [bottom] One zero notch (weird, I know) endlink with a noticeable scratch on the right-hand side. $75 [sold]


Crowns

Bump - I have also now replaced all of the faulty springs on the 7912 and removed almost all of the rust spot mentioned. Same price!
