France, attributed to Gaye, Lamaille, & Co., a fine, Aesthetic Movement, porcelain paneled hour repeating carriage clock, the gilt, Cannelee variant case with folding handle, the sides set with panels depicting a potted flower in blue, on a cream ground, also with floral ornament, and with blue, wheatear border, the Arabic numeral dial with ornament matching the side panels, blued steel spade and whip hands, two train, 8 day movement with lever platform, striking the hour and half hour in passing, and repeating the last hour on demand, the back plate marked "Patent Surety Roller", and 1813 case with minor marks and spotting, minor losses to gilding, front glass replaced, rear glass with glue residue, panels good, dial good, hands replaced, movement running, striking, and repeating correctly. The Patent Surety Roller mark refers to an extra wheel, geared to the minute wheel, having a disc with crescent cutout which blocks the star wheel and prevents the hour from advancing accidentally due to a shock. The crescent lines up with the star wheel at the hour, allowing it to advance without obstruction. The mechanism was invented and patented by Moritz Immisch, and the rights purchased by Gaye, Lamaille & Co. in 1880. This clock was sold at Christies, London, on Feb. 20, 2008, lot 33.
