This week we spotted a cool, under-the-radar release by Bamford Watch Department. Not really a general public release and rather a special custom job for a few select notable clients of the brand, BWD has applied its trademark military-grade PVD treatment to the Cartier Nail Bangle. Best known for its Rolex customization service, this is the first time we have seen the technique used on jewelry. It goes without saying, the Cartier bracelet looks fantastic blacked out and will certainly turn some heads. One interesting thing to note here, though, is that Cartier does not produce these bracelets (just like the LOVE bracelet by the brand) in steel or silver. They are only available in precious metals, including several gold options (white gold, yellow gold and rose gold) and platinum. It's one thing to give a metal Rolex Oyster a black upper, but it's another thing to cover gold and platinum in black.
