This is absolutely groundbreaking. Last I heard the CNC factory which works with tungsten only did Daytona cases. Sign me up to test out one of these asap!

Very interesting indeed. Hopefully they'll be offered with a variety of different dials to choose from.

Interesting. But first they need to rep a full clone daydate movement like they did with SA4130, 3235 etc

Shown here advertised with a VR3255, but it's clearly a 2836 with deco plates

This is a breakthrough. Curious about their price.

My guy this the rep game, lower your dose of hopium. The movement being falsely advertised is a good example of why I don't get excited. Who knows maybe just the case is made with it and the bracelet is still shitty, rattley stainless.

I'll believe it when I see it, also the longevity of the coating,etc withe copper tungsten hybrid.

Not just the longevity also how the skin reacts to the compounds here

This is an interesting development indeed. Tungsten-Copper (W80-Cu20) has a density of 15.15g/cm3, which is tantalizingly close to 18k gold at 15.4g/cm3 (assuming it’s Au75-Cu12.5-Ag12.5), and WAY higher than 904L stainless steel at 7.9g/cm3.

Its density, similar to that of gold, allows tungsten to be used in jewelry as an alternative to gold or platinum. Metallic tungsten is hypoallergenic, and is harder than gold alloys (though not as hard as tungsten carbide), making it useful for rings that will resist scratching, especially in designs with a brushed finish.

Because the density is so similar to that of gold (tungsten is only 0.36% less dense), and its price of the order of one-thousandth, tungsten can also be used in counterfeiting of gold bars, such as by plating a tungsten bar with gold, which has been observed since the 1980s, or taking an existing gold bar, drilling holes, and replacing the removed gold with tungsten rods. The densities are not exactly the same, and other properties of gold and tungsten differ, but gold-plated tungsten will pass superficial tests.

Gold-plated tungsten is available commercially from China (the main source of tungsten), both in jewelry and as bars.

So after talking to my TD about the watch. They said it is real but it weighs 135g. Lol that's the same as the stainless one. A solid gold daydate would be in the 220+ gram range.

Have a hard time believing that . The cost and effort to produce would be higher which at the same weight would produce no extra value

Been wanting a new DayDate 36mm or 40mm. This is an interesting development. I look forward to a 3155/3255 movement in the future. Hooefully they don't end up being $1K though lol

It depends on the composite. If it's a 75-90W then sure you can match weight but guaranteed it's a 50W composite.

the problem often is the color - every yellow gold day date or sub i've seen the yg looks like someone went over it with a highlighter
