Hey guys. Thought I'd drop in to say hello. Also wanted to share some analysis of 20mm spring bars I've "discovered". For the past couple of years, I've sworn by ST (Startime) spring bars. Unlike most rep and aftermarket bars, the springs don't crumple, the ends are nicely rounded, and they are made in Switzerland. They really are terrific. But I have an account at a part supply company called Beco-technic in Germany. I've ordered stuff from them a few times, but never thought of trying their spring bars until my most recent order. To my surprise, they are superior to ST bars and I suspect genuine Rolex bars are made by the same factory. Side by side, the ST bars are nearly identical to the Beco-Technic (BT) bars. The ST bar ends are rounded, and the BT bar ends are conically tapered: Now here is a comparison of the BT bars (on the left) and gen bars (on the right). Both ends are conical: Keep in mind, that these observations are based on a random and very small sample size and no two spring bars are identical . Now here is a shot of all three together (ST on left, BT in middle, Gen on right: Conical or rounded, I don't think anyone will care. But a more important contrast is the strength of the internal springs. I've always found the ST springs are "noisy" when compressed. The BT and gen are much quieter. Further here is some VERY unscientific measurements of the force required for full compression (using a kitchen scale). The gen bars, are not new, but measured 506 grams on the scale; equivalent to 4.96 Newtons (if my math is correct. I have a Physics degree but I don't remember jack [censored]): The brand new BT bars measured a whopping 580 grams (5.68 N): And finally, brand new ST bars averaged 380 g (3.72 N): Had the gen bars been brand new, I imagine the springs would be slightly stronger. At any rate, I think my go-to bars from now on will definitely be the Beco bars. If you try to order from them, keep in mind you will need to be approved. Also, I had a lot of trouble accessing their website recently (www.beco-technic.com). I'm in Canada and could not load the page for unknown reasons. So I changed my IP address to Germany and it worked fine. Odd. Frankly, I think 20mm ST bars (or equivalent) are just superb for any watch that accepts them. But the BT's are as close as I have ever seen to what you would get from RSC.1 point

A7753 is not as easy as ETA 28xx to service. You should find a watchsmith or a member to repair that1 point

Stem should be removed in winding position on this movement. Your keyless is out of order now. The winding pinion is not in place. You can try to shake a little bit the movement, that worked once for me. Otherwise you need to disassemble. Found this on another forum : "The problem may be in the fact that you are only applying "moderate" pressure, in my experience the 7750 takes a strong push on the set lever pin to allow the stem to lock in place. The other tip is to always remove the stem in the winding position, where the clutch pinion is pressed up against the winding pinion and prevents it from falling out of place, if you remove the stem in either the dateset or time setting the winding pinion will fall out of alignment."1 point

This little beauty has taken a total of 8 months to build which included a fully remachined case to take the gen spec dial and bezel, relumed hands and dial by Kenny, movement and case work and installation by Micky which included new Daytona A7750 fettled and COSC timed, new crystal and expert installation. Ive not seen one like it before and I think it was worth the build cost. Hope you like her. AJ1 point

I used the espresso as the water in the mixture, paint, and a small anount of dark power so it doesn't appear so fresh, all very delicately applied as it tends to be overdone easily.1 point
