Patek Philippe ‘Big Logo’ folding clasp in steel and gold for the Nautilus 3700

Original Patek Philippe ‘Big Logo’ folding clasp in steel and gold, suitable for the Nautilus Ref. 3700.

Used condition; it is highly likely that it has been polished once. The clasp can also be adapted for use with the steel version.

Unfortunately, the 18-carat gold Calatrava cross is missing. Please assess the condition and details from the photos.
