Up Close With The Incredible Patina Of The Panerai PAM382 Bronzo “Chronopassion”
Yesterday I posted photos of the incredibly unique Panerai Submersible PAM 382 Bronzo, owned by Laurent Picciotto of haute horlogerie retailer Chronopassion in Paris. After ten days of beach wear the watch looks like it’s an ancient artifact. Laurent kindly sent me additional photos of his unusual Bronzo and here they are.
Back to top.
Because bronze is a copper alloy, the surface copper oxidises, giving it the patina seen on the watch. The green bits are all the results of the oxidisation of the copper. The Statue of Liberty is clad in copper, hence its green colour.
Exposure to seawater – Laurent went swimming and kite surfing – will accelerate the surface changes and also produce a much more pronounced patina that you see here.
But the patina actually protects the alloy underneath as it’s a surface change so it is a good thing. That’s why antique bronze objects are green and last so long.
