Identifying Vintage Longines Bracelet Maker Stamp

Hey everyone,

I just scooped up this lovely Longines, and I was hoping someone here could help me identify the bracelet maker based on the stamp inside the bracelet/clasp.

Appreciate any thoughts

No idea, unfortunately, but it’s a gorgeous watch/bracelet combo!

Given the quality and snugness it could be a Gay Frères bracelet. They supplied to Longines, Omega, Patek Philippe, Vacheron, AP, Rolex.

Is there a “GF” stamp or a visible ram / chamois head on the (end)link? That would confirm. The style is GF from the late 50s. DA could mean Deluxe Automatic.

As much as I'd love it to be a Gay Freres bracelet, I do not see any other stamps on the bracelet :L

Thanks for the additional photo's! Such a beautiful watch and bracelet.

This is going to be hard without any stamps or assay marks. Did the deluxe come with an extract from Longines (not free anymore - its around CHF120) or even a certificate (CHF300)?

That should point to which market it was shipped and maybe give some clues on which manufacturer they used, to me that bracelet looks correct and not aftermarket.

If its UK, it could be David Shackman & Sons (the D or A on its own does refer to early 50s...) but I am just making assumptions now.
