It's bronze. It doesn't oxidise. It's not entirely inexpensive but it definitely seems worth it. The Bellytanker Bronze by the 25-year old brand Bell&Ross definitely makes you want to strut around with it on your wrist, unabashedly.
The Bellytanker Bronze derives its name from the hanging emergency fuel tanks on the bottom of old fighter planes, also known as the 'belly'. The 41mm chronograph features a rather distinct, vintage style which may come across as reminiscent of the classic Daytona, but that's not the case entirely. Limited to 999 pieces, the new Bellytanker features a black dial encased by a tachymeter bezel including gold numerals. The dial displays slim, gold hands, Arabic indices and a circular date window at the 4.30 position.
Water-resistant to 100m, the Bellytanker Bronze is made of – you guessed it – bronze which doesn't oxidise or change colour as is the case with other bronze watches, This is because of the lacquer which coats the material to keep the oxygen from doing what it's supposed to.
The Bell&Ross BR V2-94 Bellytanker Bronze chronograph comes equipped with the automatic calibre BR-CAl.301 and sits comfortably on a black calfskin leather strap.
