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.

      Epilame / Fixodrop

      By VWatchie · Posted

      Maybe it's just a coincidence, but note how the epilame-treated surface is illustrated in @Waggy's post. It looks like the oil is exposed to a binder (epilame!) so that it can't move sideways.

      The epilame under the oil will also be removed  Unless the oil makes a barrier between the epilame and the escape teeth 😅 I think i need two strong coffees now 🤣

      If we use the rub-off epilame method of pallet stones (run dry for a few minutes before applying the epilame) where will the oil go/be transported when it is pushed away from the impulse surface by the escape wheel teeth? Onto the epilame-treated sections of the pallet! Once the oil has been applied/transported to the epilame-treated sections of the pallet where will it then go? Nowhere as the oil will remain on the epilame. So, perhaps the run-dry method defeats its intended purpose leaving the pallet impulse surfaces dry!? If, on the other hand, we do not remove the epilame from the pallet stones where the escape wheel teeth come in contact with them I'd expect more oil to remain where we want it and need it. Yes, I agree, that is the question, and my gut feeling tells me that is exactly the case. Epilame was created to have an adhesive trait and the oleophobic property is just a side effect.

      Might that be the viscous nature of oil resisting gravity H  ,  we have been comparing water and hydrophobic surfaces which are similar in principle but water is much less viscous than oil. I guess what we trying to discover is if epilame also has an adhesive trait as well as being oleophobic. Plus the oil dropet has very little mass for gravity to work on, like watching tiny water beads that can grip onto vertical glass until they are connected together to increase their mass then run down. Gravity isn't the only factor at play when oil is placed on pallet stones. The oil receives a lot of bashing that may push it out of position ? Thinking about it if the oil stays in position for 10 minutes enough time for the escape wheel to scrape off the epilame , then  a walled in lubrication has been achieved,  the epilame is no longer beneath the oil ( possibly mixed into the oil )

      But it also makes it seem less susceptible to gravity. If you place a droplet of oil on an epilame-treated surface the droplet of oil will still stay in place even if you then flip the surface from a horizontal to a vertical position. That is, the oil droplet remains anchored, and that's the purpose of epilame. If it was just a matter of creating an oleophobic surface we could probably use other, less expensive, methods!? I don't know @Waggy but my gut feeling tells me you're spot on (pun intended!). I believe the oleophobic property is a side effect of epilame which is designed to keep the oil anchored.
