Is the rotor of a 2824 movement compatible with an sw200? I see gold after market rotors on ebay and other sites for 2824 but my watch runs an sw200. Some says sw200 is a clone of 2824 and parts are interchangeable and some state no. Does anyone know definitively regarding the rotor? Thanx

I think you understand that there is no gold in these, but a plating of similar color?

I would like to find a real gold one.

Really. I could not weigh it precisely but a standard 2824 weight is approx. 2.5g with the bearing. And I don't know what alloy it is made of, but a density of 9 kg/dm3 shouldn't be far off. Gold is 19.25, so it would need about 4g, at today prices that is about 200 USD. Plus very optimistically the same would go the specialist which makes this as an one-off, there you have an 400 USD upgrade for your Invicta watch. In my opinion there are better way to spend that money.

My goal originally was to drop one of the gold color rotors for a 2824 into my sw200 Invicta. A modest upgrade. Then later I got the idea to build a Submariner 16610 with upgraded lume to blue Chromalite sapphire case back and real gold rotor. Submariner in red. A prototype with some of the finest submariner features fit together into one watch.

Yeah not very realistic at all. I can guarantee you no solid gold 2824 rotors exist. Also you ain't gettin' any chromalight. Not without some connections in Rolex.

I can obtain bgw9 lume they sell it online. There is notilumnia blue as well both almost identical in quality to Chromalite. The rotor idea was gold plated 18 or 24k. My idea was to buy the 16610 parts mostly original though a few after market maybe could be swapped. I would find a used worn dial and have that refinished to new but with bgw9 lume job and Submariner in red. Gold plate the rotor, wherever they would do that, and add the sapphire caseback. Voila. I have to find affordable parts and a place to plate the rotor. Thoughest part might be luming the pip on the bezel with the blue lume. Dont know if a ceramic insert exists for the watch but aluminum would be fine if it was original. The goal is NOT a fake Rolex but an inspired prototype homage not for sale but personal use.

You are very unlikely to find just bare chronometer movements to buy unless they've been taken out of a watch, and there is a reason why these might be taken out to be sold. Why does the chronometer certification mean so much to you? It's nothing more than a marketing gimmick these days. If it's just for yourself wouldn't it be enough for you to know that your movement is just as accurate as a chronometer rated watch? COSC has what I consider to be rather relaxed requirements for granting the chronometer certification. Most ETA  movements can achieve the COSC standard for chronometers with a little bit of regulation.

Where can a watch be sent orther than COSC to obtain a -2 to 2 sec per day standard? Who will test and work on the watch to obtain that standard?

A watchmaker makes a movement or accurizes an existing movement, then it's sent to whichever organization to get tested. If it gets past all the tests they stamp their seal of approval on it and it officially becomes a chronometer. Only Rolex observes a -2/+2 standard(superlative chronometer) as far as I'm aware and don't expect them to put the "superlative chronometer" lable an any watch other than their own.
