Bronze watch natural patina1/15/2024 Liver of Sulfurįor comparison, the elegant and even patina of this Panerai is something that has naturally progressed at the hands of its owner, Hisham Mardam-Bey. When attempting these longer periods, intermittent cleaning with hot water and a cloth will help ensure a more consistent pattern of patina. In the case of the Zodiac Super Sea Wolf seen above, an external coating meant that the vinegar fuming process would take far longer than normal, with this result coming after three subsequent days of 24-hour fuming sessions. As time goes on, the fumes will start working their magic, and before long your shiny bronze beast will start to take on a darker appearance. Setting the container aside, the first few hours will be like waiting for a kettle to boil – little to no change will take place. The goal is to seal the watch in the container with the fumes, without it coming in physical contact with the liquid. To start the process, place the watch in a sealable container, raised up off the bottom, and add in your liquid of choice without getting the watch itself wet (remove its strap before beginning this process). Alternatively, ammonia is an equal, if not slightly more effective, option. For those looking for an easy solution around the house, any type of vinegar - white vinegar, apple cider vinegar or others – is the most likely candidate you’ll come across.

Innumerable hours of vinegar fuming led to this interesting and very uneven pattern on the Zodiac Super Sea-Wolf 68, whose case was initially a very light yellow with a micro-blasted finish. Exposure to moisture in the air, saltwater, and general shifts in climate will all assist in letting your bronze watch evolve day by day, but as many fans of the metal have discovered, there are a number of tricks out there that can assist in significantly expediting the process. Once again, the Carl Brashear models from Oris seem by far the quickest to start turning darker and more muted, though the offerings from Tudor, Panerai, and Montblanc do not seem to trail too far behind. Again, depending on composition, and sometimes depending on whether or not a manufacturer has applied some sort of protective coating to the metal, certain bronze watches will inherently age faster than others. Today’s topic focuses on the pros and cons of aging bronze naturally versus with chemicals.Īs mentioned in part one of this series, one of the more desirable traits of any bronze watch is how the metal will patina with age. This column addresses the various aspects of owning and caring for a bronze watch that extends beyond the obvious passion for patina. This is the second article in a three-part series on bronze watches by contributing writer Justin Mastine-Frost.
