Judex 127B

Description

If there ever was a price for a movement, constructed as weird as possible, the Judes 127B would have won it.

What the inventors were thinking, when they developed this odd and not really understandable construction will probably remain a secret forever.

Even the base plate of this well made movement shows an interesting accumulation of ruby bearings, all in the lower right quadrant.

Even more strange is the attached and screws additional bearing at position 7:30, which containls only a metal drilling and no ruby.

Even in this state, the gear train leaves us with many questions, as it consists here only of the mainspring barrel, the directly driven center minute wheel and then nothing.

On the other end, there’s the seconds wheel (which does not contain a drive, but only a pinion) and the filigree escape wheel.

Only the balance part is standard: A two leg screw balance, which is beared in two KIF Protechoc shock protections and beats with 18000 A/h regulates a traditional swiss pallet lever escapement.

The effective length of the hairspring can be adjusted at the hairspring key only.

So far the standard parts, now there’s a new oddity:

When the lower gear train bridge is mounted, you recognize, that it only bears the minute and escape wheel. The pinion of the seconds wheel (without drive!) is brought out in a rather larger hole.

Now, on the second floor, the gear train is completed:

The third wheel has got a very long axle and is beared by the metal bearing on the base plate, described above. It also engages with the minute wheel below the lower gear train bridge.

Now, there follows the directly driven center seconds wheel, which engages with the third wheel and is driven by a double gear, which engages (below the gear train bridge) with the seconds wheel.

So, altogether we have an almost conventional gear train with a directly driven center seconds indivation and a seconds wheel at 6 o’clock.

In the side view, you can see, how the upper bridge bears four(!) axles, those of the center seconds wheel, the third wheel, the seconds wheel at 6 o’clock and the double drive pinion.

On the dial side, however, the Judex 127B looks really famililiar with the yoke winding system and the KIF Protechoc bearing.
