Gustav Becker 2 Weight Wall Clock Made in Tschechoslovakia (Czechoslovakia)

I recently repaired this Gustav Becker two weight wall clock. Is is interesting in that the back of the movement is marked “Made in Tschechoslovakia”. This means that the clock was made between the end of World War 1 and 1926. See The Gustav Becker Logos. A post on the NAWCC message board talks about Gustav Becker Clocks Made in Tschechoslovakia. The clock also has a case different than I have seen before – the light color wood is very beautiful.

The case is 35 inches tall and 14 3/32 inches wide. The dial is silvered brass with printed numerals. The dial’s minute track is 6 3/4 inches in diameter (outside) and the minute hand is 3 9/16 inches long. The clock strikes hours and half-hours on a long gong rod.

The bottom of the movement has retainers to hold the pulleys when the weights are removed.

The front of the movement has serial number 549.

The rear of the movement has the following markings:

Left circle: Gustav Becker GB Frieb. : Schl. Braunau : BOEHM

Right circle: Medaile D’Or


Made in Tschechoslovakia

Note: I posted this clock on the NAWCC Message Board, and thank John Hubby for the following reply:

“This clock was made at the Braunau, Tschechoslovakia factory (was Bohemia before WWI) most likely in late 1925, but finished in 1926 at the GB Freiburg, Silesia factory after Gebrüder Junghans took over GB operations at the end of 1925 and the Braunau factory shut down.  That’s the reason for (a) the Braunau GB logo and “Made in Tschechoslovakia” stamp, and (b) the low serial number.  Junghans discontinued the long-running serial number series that had been in use both at Freiburg and Branau, and with only the Freiburg factory in operation they started a complete new series at number “1” for each of several types of clocks including these weight driven models.  The remaining stock of unfinished movements, clocks, cases, etc were moved to Freiburg for finishing after the takeover, and you can find movement designs from both Freiburg and Braunau in the same serial series.  The highest number for the weight driven clocks goes up to about 2500 over the 1926-1928 period.  I’ve not found any weight driven clocks (except for chain driven grandfather models) made at Freiburg after 1928.

You have a very nice example typical of the Braunau clocks made after WWI, with fine wood case and beveled glass in the door.  Had this clock been finished at Braunau before the Junghans takeover, the serial number would have been around 922,000+.  The Braunau factory had its own set of serial numbers different from Freiburg that ran from 1888 to 1925;  Freiburg numbers started around 1850 and the highest Freiburg number before the Junghans takeover so far recorded is just under 2,510,000.”

Note: later research has shown that the Braunau factory may not have shut down in 1925 or 1926. See the succeding posts on the NAWCC message board for more information.

Repair job 5549. The movement had little wear and needed no bushings. I polished the pivots, and replaced a broken tooth in the hour wheel. I installed new gut lines for the weights.

  1. Bill, nice you still response to an old thread!
    And your references are exquisit. Rare in a
    web where lots of “experts” talk about
    clocks by just parroting others.

    May aim is to track down the manufacturer
    of those cheap mades called “Silesia” (trademark, mainly P42s)
    you find tons of at EBay.

    Center marked GB, no serials. Cheap anchor escapement
    and cutout thinned brass. I consider them all made by Junghans after WWI (ab)using GB big name when they were already on dire straits. Silesia in reference where GB begun – in Schlesien = Silesia (Schl. on the clocks)

    NAWCC is not conclusive and John is off since wuite some time. Hope he is

    Let me know what you think.


  2. Approximately 2 1/2 to 3 1/2 pounds, but it takes experimentation to find the optimum weight. First, the clock should be overhauled and put in beat. Then find what weight is just enough to run the clock, then add about 10 to 20 % for safety margin.

  3. Beautiful clock! I just inherited a similar one but it is missing the weights. Do you know the weight and size of the weights for this clock?

  4. Hello, I need help understanding the approximate year of manufacture of my clock. I have a Gustav Becker 2-weight wall clock, stamped ‘Made in Tschechoslovakia’ on rear of the movement. The P27 movement is the same as described in the posting & the link above, with the exception the serial number. The serial number is #818442, a fairly high number in my mind, considering it has been reported Junghans discontinued long-running serial numbers at its factories both at Freiburg and Branau. Confusing matters further is the statement the replacement factory in Freiburg started at number “1,” but the highest serial number for the weight driven clocks goes up to about #2500 over the 1926-1928 period. Could you please help me understand what I have? Thank you. Best regards, Chris

  5. Hello,I recently bought a Gustave Bekker long wall clock+-1mtr long with moon phase,very rare clock,someone has lost the gears that work the moon dial,I am trying to find these gears or a diagram of what they look like.
