Gübelin/GruenSat, 01 June 2013 02:42Hi Guys, The caliber 411Fri, 31 May 2013 18:40This is the caliber 411, a 15 jewel movement that is 10.5 ligne or 23.7mm in diameter. Almost all parts will interchange with others in the 405-series. The only difference between the 411 and the 421 is the size; other wise it is fully interchangeable. These movements are always marked with the caliber number in the space next to the balance wheel and the pivot jewel for the escape wheel. The caliber 420sscaliber with indirect sweeps-seconds; Fri, 31 May 2013 15:34This is the caliber 420ss, a 17 jewel movement and is 11.5 ligne or 25.6 mm in diameter. This is a movement with an indirect sweeps seconds feature. Almost all parts will interchange with a 405 and the sweeps parts will interchange with the 405ss. The only difference between the 420ss and the 410ss is the size; other wise it is fully interchangeable. These movements are always marked with the caliber number in the space next to the balance wheel and the cap-jewel for the escape wheel. The caliber 179Fri, 31 May 2013 13:53This is the caliber 179, a 15 jewel movement and is 9-3/4 ligne or 22mm in diameter. Although these are commonly marked on the pillar plate with the caliber number, usually in the space between the escape wheel finger and the train bridge, occasionally they are unmarked. The key-less works (aka the setting bits) are diagnostic for this movement. It also appears in Alpina marked watches (the cal 575), and Marc Favre marked watches. The setting works on these are very similar to the cal 157 which is patented by M. Favre in 1925. The caliber 157Fri, 31 May 2013 04:04This is the caliber 157 and is a 15 jewel movement that is 8-3/4 x 12 ligne or 19.4mm x 27.07mm. This is one of the Quadron movements and is the only one that is 15 jewels. These are clearly marked with a caliber number often on the pillar plate next to the escape wheel. The caliber 421Fri, 31 May 2013 03:43The caliber 421 is 15 jewel movement that is 11.5 ligne or 25.6mm diameter. The caliber number is clearly stamped next to the balance wheel on the pillar plate. The caliber 430Fri, 31 May 2013 03:35This is the caliber 430, is 17 jewels and is 8-3/4 x 9-3/4 ligne or 19.4mm x22mm. It is similar to the 435 and is also related to the Curvex 440. This caliber is clearly marked with the number between the barrel bridge and the balance cock. The caliber 435Fri, 31 May 2013 03:30The caliber 435 is 17 jewels and is 8-3/4 x 9-3/4 ligne or 19.4mm x22mm. This movement is similar to the Curvex caliber 440 and there is a fair-degree of interchangeability in the parts. This caliber is clearly marked with the number between the barrel bridge and the balance cock. The caliber 405the work horse of the 1940s; Fri, 31 May 2013 03:13The below is a caliber 405, 17 jewel movement and is marked next to the balance wheel with the caliber number.
