The hands on my Mondaine clock are bent.

This is an occasional problem usually associated with moving home and the clock getting knocked.

Mondaine produce a high quality product at quite a reasonable price, but the engineering and design challenge in replicating the look of the actual station clock has presented some problems for Mondaine.  The second hand has, as you know, a large spot on the end which replicates the signal used by guards or conductors on the trains to let the driver know that it is safe and ready to move off.  Excellent so far!  However, this spot puts a strain on the pivot at the motor and makes the second hand unbalanced.  To rectify this, Mondaine has put a counter-balancing weight on the opposite end.  This is a very fine balance which can be upset if the clock receives a knock.  Your first port of call is the Mondaine Service Centre which will rectify the issue (see where can I get my watch serviced above).  Alternatively, use a local clock maker who could do the job for you.  If you wish to carry this out yourself, it can be done.

The remedy is easy, but needs careful attention.  You will need:

  • a soft cloth on which to rest the clock face down
  • a small to medium cross-head screwdriver
  • a very small cross-head screwdriver
  • a very sharp bladed knife or Stanley blade
  • a small pair of square end pliers
  1. Place the clock face down on the cloth
  2. Remove the battery (ies)
  3. Remove the four large screws and take off the back of the clock
  4. (Large clock only) Remove the power input at 6.00 position.  Gently use the pliers to to unscrew the outer ring and push the socket clear of the clock.
  5. At each stanchion around the clock on which the back sits, there is a screw.  Additionally there are screws between the stanchions.  Remove these also.
  6. Withdraw the whole back of the clock from the frame.
  7. (Small clock) there is a “sellotape” seal joining the clock and the glass.  Slide the sharp knife around the join to split the glass and the clock.
  8. (Large clock)  As above, but there is a synthetic rubber seal around the glass which needs to remain on the rim.  If it comes off, it is difficult to put back, but it is not the end of the world if you cannot get it back on; the clock can still function.
  9. Carefully turn the clock over.  If the second hand has become bent or unbalanced gently press the centre to ensure that it is fully home.  If it is bent, try to spot at which point it becomes distorted and use this point as a fulcrum with your finger and bend the second hand up or down depending on what has happened.  DO NOT bend the whole second hand as this will put a strain on the pivot mechanism and you risk distorting it and making matters worse.
  10. Replace the glass in the frame and replace the back carefully aligning the screw holes holes.
  11. Reverse the above steps.

    1. You should only use Duracell batteries on Mondaine clocks, they have power and durability. If the clock has been moved it is possible that the second hand is being obstructed by the minute hand, or is being retarded by touching the glass, so check free movement. If none of this answers, suggest you send it to Mondaine repairers – see separate post.

  1. I was given a Mondaine yesterday (my birthday!) after requesting one for sometime. I am really pleased to finally have one but find the strap to be quite small for my wrist. My wife tried to discover (via websites and at stockists) if the strap length is a standard length. She could not get a definative answer. So whilst the website etc can tell customers the width I believe the length is also important – especially as I want a secure length strap so the watch remains on my wrist and doesn’t fall off. As a man of average height and weight I don’t think I have abnormally sized wrists.
    The length of the strap with holes in it is 110mm – do you make longer ones ? (130mm would be much better).
    Could longer straps be offered on future purchases?

    1. You are talking here of the Big Date version of the Mondaine watch group. Ordinary date watches have a ring of numbers from 1 – 31 which gradually rotates as the dates change. For the most part, these dates are small because of squeezing 31 numbers onto the dial. Some manufacturers, notably Rolex, put a magnifying glass on the crystal (glass) to make the dates appear bigger.

      Mondaine tackles this small date problem from a different perspective. They have two concentric rings of numbers. The outer, larger one, has 0 – 9 repeated and the inner one 0 – 3 repeated 3 times. This gives the big date effect. The down side (?) means that you have to change the date at the end of every month instead of those months that don’t have 31 days.
