JDF just launched a tungsten gold rolex day date with correct gold weight
- Thread starter molivio
- Start date
Tungsten-Copper (quoting from wikipedia): "The material combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine." [reference]
Apparently the feeds & speeds for machining CuW depends on the ratio of the metal mixture (technically it's not an alloy). Quoting from eaglealloys.com "Copper Tungsten Alloys use speeds and feeds similar to Gray Cast Iron. Copper Tungsten Alloy become easier to machine as the copper content increases. The more tungsten content present the more care must be taken when machining. Carbide tools are suggested for most cases and a coolant is optional." [reference]

Maybe… to have the same weight as the gen, the whole watch case and bracelet would have to be made from W80-Cu20 and then plated with yellow gold. While this is possible, it feels unlikely given the price, but maybe not. Everything is CNC’d, so maybe it’s as simple as changing the metal stock and setting different feeds and speeds for the machine.

I saw the add on the puretime, couldn’t believe my eyes, I just typed my supplier, that is close friend with the JDF boss! So let’s see what he says tomorrow
Its too cheap to be legitimate. It's the same price as stainless DD40. Every single TD I emailed said they haven't weighed it and the factory won't weigh it but says it's very close to gen. Suspicious as hell considering they like to always point out when they havs innovation on reps. It wouls be a selling point. Imo it's a hard pass
A couple things to note:
1. PT is listing it with 3 different movements available
2. Reflections or plating flaws?

If this rep is made from tungsten-copper (big if)… it would still need to be plated since copper tungsten isn’t naturally the colour of white, yellow, or pink gold.

Tungsten copper is a very different color. It's reddish like copper.This is the Movado Tungsten Carbide watch...kinda grey
Haha Puretime has taken away that special sign, with adding the extra WU-C steel
It's gone lol, all the hype for nothing?

The description for case and bracelet now says "18k yellow gold plated solid 904L stainless steel case"
Welp, ok.
Welp, ok.
No mention of weight ?
