The Sympathie is only available in white or rose gold, unlike the Hommage. The Franck Muller Replica have a much larger number of dial variations. This is either because they are produced in smaller quantities or that there are fewer on the market. This is a list of all the configurations that are publicly available, based on the same sources used to discuss the Franck Muller Replica.
The Sympathie was only available in two sizes: 34mm and37mm. This is unlike the Hommage which came in a 40mm size.
The Calibre RD 56 is used for the regular version and the RD 65 for the monopusher. Both are based on Lemania ebauche 2310, a venerable chronograph movement. In 1942,replica watches Lemania and Omega teamed up to develop a chronograph. Omega named their version of the Calibre 321 movement, which you might know as the one that went to the Moon.
The 2310 has a column wheel with a screwed balanced that oscillates 18,000 A/h. Today, watch brands are very proud of developing their movements in-house. However, it used to be considered best practice to have a highly-skilled and specialised movement maker create and design a high-quality Ebauche. You tend to do well if you focus on one thing. Many collectors still remember fondly the Patek Philippe perpetual-calendar chronographs, which were based on Lemania movement. You can see in the image below that the Hommage and the Patek Philippe 397 both use the Lemania 2310 ebauche.
Dubuis wanted to compare the watches side-by-side. The choice of ebauche is just as evident as the quality, style and level of finishing that Dubuis put into his early models. He used the finishing techniques which made Patek Philippe movement so desirable,zenith replica such as Cotes de Geneve (mirror polishing), anglage and mirror polishing. All of these things helped the movement win the Poincon de Geneve.
