Rare English Six Minute Tourbillion

A fine large early 20th Century English tourbillion in a silver open face case and deck box.  Gilt half plate keyless movement with going barrel.  Rare flying 6 minute tourbillion carriage rotating once every six minutes.  Plain cock with diamond endstone. Compensation balance with freesprung blue steel overcoil hairspring. English table roller lever escapement. Screwed in jewelling, escape and lever pivots with endstones. Signed white enamel dial with subsidiary seconds, Roman numerals, blue steel hands. Substantial plain silver open face case with gold hand set, hinge and thumb pieces, gilt winding button, silver  bow.  Maker's mark “W.B” in a rectangle and number corresponding to that on the movement.  Fitted in a three tier mahogany deck box with brass furniture, signed and numbered circular bone plaque on the lid.  Two spare flat glass crystals.

A very rare variation on the tourbillion rotating escapement.  Although the carriage resembles that of a centre seconds karrusel it is directly driven by the train.  The carriage of a karrusel is passively rotated by one of the train wheels.  This carriage  rotates more slowly than a one minute tourbillion as it also carries the fourth wheel.  Examples of this form of tourbillion are very rare, this example being in excellent condition and benefiting from having a deck box.  The firm of Joseph White manufactured watches in Earlsdon, Coventry.  Much of their high quality output was sold to the Admiralty.

Rare Subsidiary Seconds Verge by Tompion

A rare late 17th Century verge by Tompion with subsidiary seconds dial.  Deep full plate fire gilt movement with pierced tulip pillars.  Fusee and chain with worm and wheel barrel setup between the plates.  Pierced and engraved winged cock, pierced and engraved foot.  Plain steel balance, silver regulator disc.  Lateral steel stop lever, a brass arm acting on the edge of the contrate wheel.  Purpose made signed white enamel dial with subsidiary seconds, Roman and Arabic numerals, blue steel beetle and poker hands.  Purpose made matching silver pair cases, hallmarked London 1769, maker's mark “SC”.

This watch formed part of the Burton collection, see “The Watch Collection of Stanley H Burton Warts and All”.  A rare early Tompion, no. 1303 (the circled dot representing a thousand), with subsidiary seconds.  Until the application of the balance spring watches were not accurate enough for the indication of seconds to be useful.  There are less than a dozen examples of Tompion's watches with subsidiary seconds recorded.  The dial plate is stamped “SC” for the movement finisher whose mark is found on many Tompion watches as well as some by Daniel Quare and James Markwick.   The mark might be for Sampson Crooke.  This The quality of the movement was still appreciated enough  80 years after its manufacture to warrant it having a new dial and case made for it.  See “Thomas Tompion at the Dial and Three Crowns” by Jeremy Evans who we thank for his help in providing information about this watch
