This is an antique one-piece case (circa 1860), bell-striking French carriage clock by the famous clockmaker Japy Fr. Please look carefully at the description and pictures, as they all form an integral part of this sale. The company founder was Fr.His company was based in Badevel and initially produced basic watch movements. The company grew to become the most singularly important watch/clockmaking organization in France, with offices in Badevel, Beaucourt and Paris. He was particularly important in the development of hour and quarter repeater carriage clocks as well as calendar works etc. Possibly the greatest accolade he was paid was winning the Gold Medal of Honour in the 1855 exhibition.
His company grew to be very diverse, even to the extent that the first petrol engine to be in a Peugeot vehicle was made by Japy! When acquired, the clock had obviously been put aside for many years and was in quite a neglected state. Despite its condition, after restoration, it has come back to life and in good condition. Its height with handle raised of 6. Inches makes it - later referred to - a Calibre N.2 - the middle of the three largest so-called full-sized carriage clocks. The face is of the classic white enamel-on-copper construction. The Roman numerals are in excellent condition, as is the chapter ring and the blued-steel Breguet (or moon) style hands. Overall, the case is in excellent condition, other than previous work having been carried out on the cases top rail (the right side see picture), which has left a small area of missing brass. There are also a few small marks elsewhere on the case, but nothing other than one should expect from such an aged clock, being somewhere around 160 years old. The clock comes with a new 3.5mm correctly fitting double-ended key. The movement strikes once on the half-hour and the number of hours on the hour on a very sweet-sounding spun chromed bell. Including base platform 9.4 cms. Including base platform 8.3 cms. Including base platform 13.1 cms. And with handle raised 16.3 cms. Inside of the back plate bottom centre. Back of the front plate. The movement was carefully dismantled to component level and the following procedures were carried out. All components cleaned ultrasonically in a horological cleansing solution; washed, rinsed and heater dried. Wheels, arbors, leaves, levers, springs, rack, snail, pinions and pivots all checked for alignment and wear none found. Pivots polished on clockmakers lathe. Movement plates examined and pivot holes/bearings checked for wear (possible distortion, usually due to mechanical pressure, lack of servicing, or simply age-related wear) - none found. Pivot holes pegged out to remove all remaining debris (a paste of old/dried oil). The mainspring (the clocks muscle) and strike barrels were dismantled, their springs removed and checked for wear (none found).
Both springs are in excellent condition. With the mainspring having a working Geneva stop-work see. They were cleaned, lightly greased and re-fitted into their respective barrels. All components de-greased in isopropyl alcohol and then brush-polished with French chalk, which also helps to delay tarnishing, a natural brass occurrence. Movement re-assembled - all arbors checked for end shake.Contrate cock adjusted for correct depthing between the contrate wheel and escape pinion. All sinks oiled with high-grade Moebius clock oil. Stop works - were generally fitted to the higher quality carriage clocks. This device stops the mainspring from being fully wound and becoming fully unwound. Springs deliver maximum power when wound and gradually lose power towards the end of the run-down. The stop work ensures that the power delivered to the going train by the mainspring is quite constant therefore aiding timekeeping.
Naturally, it also stops the mainspring from being over-wound. As this clock has a working stop work, it does need winding every seven days. It manages the power generated by the mainspring through the going train controlling the clocks timekeeping ad is also the most delicate assembly. This is a very simple and good brass platform with an off-set club-toothed ratchet lever, individual cocks and timing screws on a steel balance wheel (typical of Japy) and in perfect working order. The following procedures were carried out.
Platform dismantled and all components (other than the hairspring), were cleaned in a 4-stage automatic watch component cleaning machine. The hairspring was cleaned in an oil-based cleaner. No rust was present anywhere on the spring. Platform polished with French chalk. Jewels checked for wear - pegged out and cleaned as appropriate.
Balance wheel, impulse jewel, fork and pallets cleaned; staff, pivots and all jewels checked for wear. Escape wheel, pinion, leaves and index all cleaned and checked for wear.Components de-greased in isopropyl alcohol. Platform reassembled, oiled with high grade watch oil, powered and timed to 18,000 beats/hr.
Once adjusted and timed, the platform now produces an even beat, a very positive action with good amplitude and the hairspring breathing correctly within the index. Like the rest of this clock, it is now in pristine condition. The faceplate, dial and hands. Are all in excellent condition, with the classic white enamel-on-copper face, Roman numerals and chapter ring, having no cracks, hairlines or missing enamel. The Roman numerals and chapter ring are very delicately inked typical of the period and in excellent condition - as are the condition of the delicate blued steel Breguet (or moon) hands.
The movement, dial, false plate and hands were re-assembled and powered while the case was being overhauled. Is a one-piece brass case, being made of highly reflective brass. As mentioned earlier, there is one area to the case where previous work has been carried out.
There is a small piece of brass missing from the top rail when viewed from the right (see picture) and no attempt has been made to repair this area. The number 295 is stamped into underside of the base platform, as are the initials H. The number 9 is stamped into the top side of the base platform.
The case was dismantled to component level and the following procedures carried out. Parts soaked for 24 hours in a warm solution of horological cleanser, washed, rinsed and heater dried.
All case components were then cleaned with a metal burnishing paste used by museums. They were then dipped in isopropyl alcohol for de-greasing. Other than the front glass, all the 4mm bevelled glass panels and platform viewing window were replaced during overhaul, as they were all quite badly damaged. They do not rattle when in situ - due to their perfect fit. As the case has been cleaned, lacquered and waxed, it will now need no further attention other than careful dusting.Microfibre cloths are excellent for this. Under no circumstances should any silicon-based or metal polishes come anywhere near the clock. Was carried out once the movement was reinstalled into its case and powered. It has now been run for four full rundowns without any issues, keeping near-perfect time throughout.
The indexs regulator arm is very close to the centre of its operational arc, which is where it should be after a complete overhaul and regulation. This is an express condition of an export sale. This is quite an early, good quality bell-striking, one-piece brass-cased carriage clock, made by the respected clockmaker Japy Fr.Following a complete and sensitive overhaul, it is now in excellent condition throughout, which has brought it back to being in good condition, both visually and operationally. This clock should be serviced every five years by a competent clockmaker to ensure optimum performance, as this is the working life of good quality clock/watch oil.
