The Richard Lange Pour le Merite, features a fusee and chain transmission. The fusee in fact, makes the watch more accurate in the same manner as the tourbillon. Just like the tourbillon, it has great chronometric value among collectors. This is the third watch produced by A. Lange & Sohne, of Glasshutte, Germany to have a fusee chain incorporated into the movement. Caliber L044.1 is a manually wound movement,that is focussed on attaining the ultimate in reliability and accuracy. The large balance wheel with eccentric weights beats at a rate of 21,600 semi-oscillations per hour. The Lange Balance Spring, is designed by a team of Lange's master watchmakers and manufactured in-house. According to the salesman,the spring is attached to a patent-pending clamp,which unlike traditional construction does not deform the spring in the stud,instead it is secured to simplify any future adjustments that might be needed. Techinical Specification: Ref. 206.25 model in Platinum Edition of 50 pieces worldwide Movement: Fusee-and-chain Caliber L044.1 26 Jewels Manual wound 36 hour power reserve with hacking mechanism. Dial: Enamel in white with Blue-steel hands Case: 40.5mm Height: 10.7mm Sapphire-crystal front and back Hand stitched aligator strap.

Thanks for the information on the A. Lange & Sohne movement. I'm not a watch maker but I can sure see that their movement is a thing of beauty. Are you going to be building a watch using one of these movements? cool10.gif

I'm not a watchmaker, I just sell watches for a living. What I admire about the caliber L044.1,is the ability to execute such a complex movement. Helmut Geyer,the senior caliber designer behind this wonderful movement at A. Lange & Sohne. Did the impossible,by combining early watchmaking techniques of utilizing the fusee and chain. Which were used in the 1400 to the early 19th Century and incorporating with the 21st Century. No words, can describe the shear brillance of Geyer's design. I'm still speechless as I'm writing this post. In answering the question if I was building a fusee-and-chain movement. The answer is no. However, I do have my eyes set on an English Lever-Fusee dating to 1890. This movement was much more accurate than the earlier Verge-Fusee which dates to the 15th Century until the mid-18th Century.
