Omega Seamaster 300 Bronze Gold Master Chronometer
Once again Omega has come up with a new proprietary alloy of its own that this time combines copper and gold. The first introduction of this novel material will debut in the new “Seamaster 300 Bronze Gold”, as the flagship model for their new line of retro dive watches in 2021. Recently we reviewed the steel editions, but this release will differ in more than just its alloy, so let’s dive on iN.The 41mm case is made of a bronze gold alloy that consists of: copper, 9-karat gold, silver, gallium, and palladium. It’s quite a mix, but Omega hasn’t revealed the exact percentages of each material. Although the Au375 engraving does guarantee the presence of 37,5% gold in this alloy. 
In terms of color Omega has stated the hue is somewhere between their proprietary Moonshine (yellow gold) and Sedna (rose gold) creations; while mentioning the use of palladium will keep the color bright and reduce the patina effect.
Mounted to the case is a unidirectional bronze gold bezel with a riveted circumference and a brown ceramic insert. Besides a pleasant color-scheme this juxtaposition of materials will provide a solid resistance against scratches and corrosion.
Just as we recently mentioned in regards to the new 2021 steel versions of this model, it’s been crafted with a noticeably thinner overall case compared to the previous 15 mm of the 2014 edition. But unlike the 13.85 mm depth of the steel options, the bronze gold model measures in at a slightly thicker 14.4 mm.
On the flip-side is an exhibition case back, which allows to view the inner workings of the mechanical movement. This modern METAS-certified caliber comes equipped with a silicon balance spring and non-magnetic escapement. The screw-on portion also features the “Master Co-Axial Chronometer” inscription that until the release of these 2021 editions was usually displayed on the dial side. 
It also comes equipped with long protruding lugs for a comfortable wrist fit, plus a screw-in setting-crown with an embossed Ω. All topped by the new domed sapphire crystal and a water-resistance capable of reaching up to 300 meters (1000 feet). 
Time is also exhibited on a brown “sandwich” dial, made up of an upper and lower dial plate (just like the steel Seamaster 300 models) with triangular hour index markers and the Arabic numerals: 3, 6, 9 and 12.
These cut-away markings and numerals are given form by the upper plate made of conventional bronze, which has been treated to create surface oxidization, creating a “brown patina” look. 
It features the iconic broad arrow hands in bronze gold, but unlike the new steel Seamaster 300 editions that have a “lollipop” seconds, this model has been fitted with a conventional arrowhead seconds hand.
These central hands, plus the hour index markers have all been filled with a well-suited faux-patina Super-LumiNova, for an enhanced legibility. As mentioned previously overall this is a very solid and legible dial stripped down to its bare essentials by removing the “Master Co-Axial Chronometer” inscription, while still retaining the “OMEGA” logo and “Seamaster 300” with its characteristic cursive font. 
Omega Seamaster 300 Bronze Gold Master Chronometer

It is based on the original 8900 caliber, but without the date display. In essence this is a no-date version of caliber 8900 and it is also a METAS-certified Master chronometer.
