Of course, what has become the trademark feature of the Carl Brashear edition watches is the use of bronze, which is entirely appropriate here for a watch paying tribute to a man who made his living wearing a heavy dive helmet made of the same material. Bronze is no longer a novelty, with many brands from Halios to Panerai having offered versions made from this ancient alloy. But Oris does a better job than most, in my opinion. In particular, the dive bezel, with its engraved hashes and numerals in relief, lends a visually interesting backdrop, where the bronze appears almost aged right out of the box, before it even starts to develop its well-known patina. The 43mm case is solid cast bronze as well and so are the crown and chronograph push-pieces, withe the latter being traditional “mushroom” shaped, which further lends a vintage feel to the watch.
