Lorch made a wide range of high-quality watchmakers' lathes in both Geneva and WW types branding them Lorch, Lorch Schmidt and L.S. & Co. However, like most other manufacturers in the field, they were also content to market models under other names with corners cut in material quality and cosmetic finish - one of the most popular lower-cost models treated in this way being the Geneva-pattern Triumph.
Lathes were available with 6 or 8 mm collets either as individual machines or, more often, in boxed sets, these being listed from No. 1 to No. 12 (and possibly higher); however, as boxes were offered separately for owners to mount their own collection of accessories, it is not always possible to categorise them exactly.
A typical set would have been the No. 2, an outfit that provided the typical watch repairer with all the basic equipment he needed. Sets 3 and upwards included such luxuries as a compound slide rest, two types of tailstock (with a sliding spindle and a lever-feed spindle), a universal faceplate and pump centre drive plate, screwcutting attachment and changewheels, vertical milling slide, pivot polisher, milling and grinding spindle, 3-jaw and 6-jaw self-centring chucks (sometimes called "Universal Chucks"), 4-jaw independent and self-centring chucks, drill chuck for the headstock or tailstock use, wheel-cutting attachment with division plate (to cut what the laymen would call gears but which are known to the watchmaker as "wheels"), a "Mandrel" - in effect a spare headstock with a "faceplate" attached used for super-precision work, a headstock that could be swung with an overhung drive pulley. Numerous smaller accessories were also offered including single or double roller rests, a variation of the fixed steady called a self-centring back steady, , saw tables, rounding-up tools, Jacot Drums. pivoting attachments, lapping attachments, wax chucks, button or crown chucks, box chucks (with eight radial-disposed holding screws), drilling plates - self-centring (a disc with a ring of holes each formed with a coned face to self-centre work), wood screw chucks, wood-turning chucks, tip-over and standard T-rests, emery wheel chucks, lantern chucks in bronze and steel, circular-saw chucks, carrier chucks, balance chucks, pin chucks formed so as able to be held in the tailstock or headstock, drive or "catch" plates for between-centres work, micrometer-adjustable boring heads, adjustable eye glasses, self-centring drilling attachments, drilling rests, indexing attachments with worm-and-wheel drive, etc. Also offered were various types of drive system, countershafts and electric motors with, on later models, a base unit complete with a motor to make the whole assembly self-contained and ready to mount on a bench.
More often to be found from American rather than European makers was a bench unit with multiple drawers and devices to hold accessories - those were often from a third-party supplier such as the one by J.H.Rosberg of Chicago with this Rivett watchmaker's lathe.
Oddly, no makers of watchmaker's lathes ever offered an instruction book - these being the exclusive enterprise of independent publishers with one of the most useful being "The Watchmakers' Lathe".
