Guba 875 new

Movements from Guba, Gustav Bauer in Ellmendingen near Pforzheim, Germany, are always quite a rarity, but this ladies' watch caliber Guba 875, here in the new version, is really difficult to find. The term "new" is pretty misleading here, since the old and new version differ in so many parts, especially on the dial side, that they are in fact two different movements. The caliber number 875 indicates its diameter of 8 3/4 (=8.75) lignes.

It's a bit difficult to say, when this movement debuted, maybe it was in the early 1950ies.

There are two noteable facts on this movement: First its red-golden color, second the ruby bearing for the minute wheel, which is pretty unusual for a movement of the early 1950ies and is responsible, that it already advertises with "17 jewels".

The Guba 875 (new) has got the classical gear train: The mainspring barrel drives the center minute wheel, followed by third wheel, seconds wheel (with decentral seconds hand at 6 o'clock) and finally the escapement wheel.

The golden toned screw balance, which beats contemporarily slow with 18000 A/h is not yet shock protected. Its precise beat frequency can be adjusted with the hairspring key only, despite the "fast/slow dial on the balance cock". These are the only two downsides on the otherwise very well made movement.

On the dial side, you see the yoke winding system with its characteristical setting lever spring. You also see the engraved caliber number. The old version of this movement differs a lot here, especially on the setting lever spring.
