Have one of these but is not really that good for the large heavy watches....like a UPO 45 Chrono on ss bracelet What is the best winder for big and hevay watches?

Thanks all Timemaster,cornerstone, Ronin, maxman, deniz21 and FxrAndy And yes! It is indeed a shame that the dealers do not give us the facts about the movements. And yes! Its is also a conondrum why metal and not jewels is used in these bearings

That sounds goooooooooooooooood. The RWGs the best God Helg! Gunnar

yes! we all want clear answers......you just have to try to get one replica, get one that you would like to wear regardless of what other thinks, if it looks ok to you tolis then get it, and go on from there...replicas unfortunately are far from perfect

Youre welcome Rolexman

The new asian 7750 movements around do not have 25 jewels in them!!! (Jewel = jewel-lined pivot hole with ruby red colour) The New 37mm Asian7750/a07.211 is larger in diametre than the asian7750 and ETA 7750 movement, and is same larger size as the new ETA Valgranges. These larger 37mm New Asian 7750 (=a07.211) movements fit well in larger watches, like the CHOPARD GTXXL Chronograph However the new 7750 around appear to have very very few jewels in them, but have more than 15 metal bearings instead (This has also been confirmed by The Zigmeister) Jewels = A jewel bearing is a bearing in which a metal spindle turns in a jewel-lined pivot hole with ruby red colour. Jewel bearings were invented in 1704 for use in watches by Nicolas Fatio de Duillier, Peter Debaufre, and Jacob Debaufre, who received an English patent for the idea. Originally natural jewels were used, such as sapphire, ruby, and garnet. In 1902, a process to make synthetic sapphire and ruby (crystalline aluminum oxide, also known as corundum) was invented by Auguste Verneuil, making jewelled bearings much less expensive. Today most jewelled bearings are synthetic ruby or sapphire http://en.wikipedia.org/wiki/Jewel_bearing So is the new asian 7750 (= a07.211) a bad movement? The Zigmeister said that, and I quote; "When you design and build a movement with metal jewels not sapphire ones, then expect to see metal jewels. This is how this particular A7750 has been build and designed. If there were no jewels, then you could blame QC, but not in this instance, QC is working just fine, all the jewels are in place and doing what they are designed to do..Many vintage pocket watch "jewels" are nothing more than holes in the brass plates, clocks are the same, the pivots turn in the brass plates." However the dealers do not properly describe this new asian 7750, and certainly do not advertise that metal bearings have been used A pictorial description of the asian a07.211 (= New A7750) movement below: First a comparison of the new 7750 (= a07.211) and SWISS 7750 and normal asian A7750 A partial breakdown of the new Asian A7750 (= Asian a07.211) As a finishing note, I hope and pray The Zigmeister or any other of our excellent watchmakers do a more detailed review on this topic so all (RWG menbers and Dealers alike) can be well educated about this and other asian 7750s around so members do not end up getting a big surprise + I will post more on this topic later Thank you Gran

Aye!!!

Ok good points you make, have edited that part as the numbesr may vary and yes The Zigmeisters comments are clearly stated in my post and anser to your question is Yes! Question is still do you want true jewels or metal bearings in your movement

Be aware that some of the new asian 7750 movements around do not have 25 jewels in them!!! (Jewel = jewel-lined pivot hole with ruby red colour) The New 37mm Asian7750/a07.211 is larger in diametre than the asian7750 and Swiss7750 movement, and is same size as the new ETA Valgranges. These larger 37mm New Asian 7750 (=a07.211) movements fit well in larger watches, like the CHOPARD GTXXL Chronograph However the new 7750 around appear to have very few jewels in them, but have more than 15 metal bearings instead (This has also been confirmed by The Zigmeister) Jewels = A jewel bearing is a bearing in which a metal spindle turns in a jewel-lined pivot hole with ruby red colour.

Today most jewelled bearings are synthetic ruby or sapphire http://en.wikipedia.org/wiki/Jewel_bearing I bought a CHOPARD GTXXL Chrono with this new larger asian 7750 movement (=asian a07.211 movement) I spotted that the red ruby colour was absent ontop of 3 gears I sent it to Domi for service, as I could see it was lacking 3 of the the usual ruby red Jewelled bearings that are typical for 7750 movements It turned out this movement has metal bearings in fact it had only few ruby red jewels were used Note that jeweled bearings are most common in a modern movement I was not at all happy with this and had the movement changed (I will post more on the change of movements in a diffrent thread later). So is the new asian 7750 (= a07.211) a bad movement? The Zigmeister said that, and I quote; "When you design and build a movement with metal jewels not sapphire ones, then expect to see metal jewels. This is how this particular A7750 has been build and designed.

However the dealers do not properly describe this new asian 7750, and certainly do not advertise that metal bearings have been used I find this not to be acceptable when not explicitly explained to the buyers, as this new 7750 is likely less expensive to produce, and less beautiful to look at, and further from the genuine in appearance Dealers to be trusted on this?

Well done!!!!!!!!!!!!!!!!

It is a large watch so maybe the 42mm size is even better looking PO of this version....I have a 4th generation PO 42mm and many feel it is a more balanced look than 45mm unless you got a huge wrist I think the PO Chrono is a better choice at 45mm and have one of those myself and I got a 19cm wrist size so it is as large a size OMEGA my wrist can tolerate

Nice UPO Franken The IWC Jones on my wrist

A beauty, I have to getr one of these too

Love two of those

Why the censored do you want to open it? and now I tried to unscew mine and it wont either...but yes it is probably just stuck

Great looking replica you got IWC 5445, Portuguese Hand-Wound, Vintage Collection, Reference 5445-01, Homage to the First IWC Portuguese Watch of 1939m The original old one THE Original IWC portuguese hand wound from 1939 with blued hands. Amazing huh!!

Also, sapphire and mineral glass is tested by dropping a 2.25 ounce steel ball-bearing on a representative crystal from varying heights until the crystal breaks and the total amount of energy needed to break the glass can be calculated. According to ISO 14368, Part 3, mineral glass must absorb 1600 to 2100x10^-4 Newton-Meters, sapphire is only required to 800 to 1800x10^-4 NM. so saphire can be brittle You cannot tell the difference between regular mineral crystal and sapphire crystal, except when you attempt a scratch test. Mineral crystal is break resistant but scratches relatively easily; whereas sapphire crystal measures very high at 9 on the Mohs scale, a rating measure of the relative hardness of various materials. Watches are often marked as scratch resistant when fitted with sapphire crystal. Very often, lines and marks on sapphire crystal are mistaken for scratches, which is actually the anti-glare coating fading off after time. Most newer fine watches are fitted with synthetic sapphire crystals. Sapphire is extremely scratch resistant and this kind of crystal will look like new for years. However, its hardness makes it easier to shatter than mineral crystals. This is usually only an issue if you wear your watch while engaged in very physical activities. In that case, you may want to look for a domed mineral crystal. The major drawback of mineral crystals is that they scratch much easier than sapphire crystals. Some say they also look "cheaper" in the way they reflect light. Others say they look "classic" on certain watches. a further distinguishing characteristic of sapphire vs mineral is how the droplet behaves if the watch is tilted off the horizontal. On the mineral glass the dropplet will cling and elongate as it starts to drip, leaving a streak. On the sapphire, the droplet remains a ball shape. You can tilt the watch and rotate it and the droplet looks like a little clear ball rolling around on the surface of the crystal

yes I see
