After doing some research on the Asian clones of the venerable Valjoux 7750, I was amazed at the positive feedback of the "Shanghai" clone as it is known. As a collector of the various mechanical chrono movements, I wanted one of these in my collection. Most of the Asian 7750 knockoffs are being used in fake watches, and the QC is therefore non existent. My research pointed to a few independent manufacturers of niche market watches who have been successfully utilising some of these movements in quality watches. I have a Precista chrono with a Seagull hand cranker (based on the Venus 175) which I enjoy and find very well made. My attention was drawn to Carlos, a Portuguese enterpreneur who established his own brand, "Prometheus". He is well known on some other WIS fora. He has put together a very nice chrono using the Shanghai 7750 movement. The watch is currently available at 200Euros or $300, which makes this an absolute bargain. I'm not going to do a review here as there are many posted already. What I can say is that I am pleasantly surprised about the overall package. The look and feel of this watch is superb! ![]() The bracelet is very well made, with very solid end links. Although links are connected with split pins, they fit well. The transparent caseback is a nice touch and the movement looks good. Very few WIS will be able to tell it is not a V7750! ![]() I really love the dial, markers and hands! Admittedly there is a controversy over whether the design was copied from another watch, but I'm not getting involved with that.... The active chrono hands are red, while the continuously running seconds hand is white. The black subdials have small concentric circles which set them off nicely against the black dial. Markings are in white and acts as a border. The design of the markers and hands are similiar. The date and day windows have a white border, and the only writing on the dial is concentrated above and below these windows. The all black and white theme works very well, with the thin red hands a small splash of colour. The lume on the markers and hands look good, but under a 10X loupe the application looks a bit rough. Lume is nowhere near the Monsters, but adequate. There is no lume on the index marker of the bezel. The 60 click bezel works well, although a bit of play is present - nothing that will upset any calculations. ![]() The pushers are great, and a direct copy of the Daytona's. Obviously being of the screw down type, they are slow to put into action. The crown screws down and there is a substantial protector present. However, the design interferes with the functionality of the crown: it is difficuilt to pull it out once unscrewed because the protectors do their job too well! The watch is rated to 200m. Quite incredible for a chrono in this price range! I tested it myself, and the claim is fair. Out the box it was running at a costant +20 per day in a 3 day cycle. (yes, I wore it for 3 days over the weekend!) Although not run in yet, I couldn't resist regulating it. After my first attempt it is running at +9 on the winder in 24 hours. Not bad at all! I bought this watch primarily for the movement, never expecting to like it as much as I do. I think this will become one of my faforite beaters!woohoo.gif ![]()
