Manufactured by Golay-Burchel of Lausanne, Switzerland the "Favorite" lathes were but one part of a vast array of horological accessories turned out by the company. Like Boley in Germany they offered a complete product range from the tiniest screwdriver through staking sets to micrometers, vernier gauges, precision drills, taps, dies, engraving machines and even electr o-plating kits. Their 325-page catalogue was a treasure trove of mouth-watering items designed to help the watch and clock repairer undertake every conceivable task.
Built in three versions - the Model 1, a 40 mm centre height traditional light Geneva-pattern machine, the Model 2 with a 50 mm centre height and the rather heavier and later Model 3--all were,  naturally, of the finest quality, built to Schlesinger standards and designed to for watch, clock, jewellery, dental, tool-making and experimental work. Painted in a "hammer-finish" lacquered green paint the No. 2 and No. 3 lathes shared many of the smaller accessories - although some catalogues listed them under different designations. Although by the mid 1950s the No. 3 had replaced the No. 2 a version of the No. 1, the 1B remained in production for many years, presumably to cater for those watchmakers who preferred a traditional lathe. However, as a larger-capacity machine the No. 3, with its ball and roller-bearing headstock was (like the English IME Model 300) able to tackle a much wider variety of jobs than most machines in this class yet still remain capable of the very finest miniature work. 
Although as heavily built as a traditional Webster Whitcombe (WW) watchmakers' lathe - and with the same 50 mm centre height - the No. 2 was a unique design. Instead of using a traditional flat-topped, bevelled-edged bed that on the Favorite was flat, with vertical sides and the headstock, tool rest and tailstock clamped in place by means of a central fastening. When mounted on a single foot (two were an option) the bed was held in a quick-release eccentric slot, allowing it to be easily removed for the close inspection of work or transferred to a bench vice where other accessories--a pivoting attachment for example--could be more easily employed.
Designed in the days before the cost benefits of a pulley overhung to the left of the headstock became apparent (as on the just post-WW2 Pultra) the 4-step headstock pulley was carried on a hardened, ground and lapped spindle between a pair of adjustable conical bronze bearings. Lubrication was provided by built in capillary-action oilers, a considerable advance on the hit-and-miss oil-can method thought to be adequate by so many competing manufacturers. Instead of a plain, collet-mounting nose the designer provided a substantial thread, backed by a long, supportive register, the intention being to provide as rigid amounting as possible for chucks, faceplates and stepped collet closers. The nose was bored to accept draw-in 8 mm collets (by screw tube or lever-action closer) and the outside face of the largest diameter of the headstock pulley carried two circles of dividing holes - 60 and 48  - with a built-in indexing pin unit. A ring of 12 holes was also drilled into the opposite end of the pulley and intended to be used as a means of locking the spindle when changing nose fittings.
Available with inch or metric feed screws, the compound slide rest registered against the front of the bed and featured fully covered and protected feed screws. The end plate of the cross slide was secured by four screws while two lever-operated clamping bolts were fitted to the top slide to ensure absolute rigidity when mounting high-speed milling and grinding spindles.
Tailstocks with sliding and lever-operated spindles were offered, the latter able to take 8 mm collets and fitted with a micrometer stop for use when drilling. None were fitted with a screw feed, the lever type being judged to have superior feel when undertaking delicate drilling. A special tailstock was also provided, of the horological pattern, for use with pivoting work..
