Case service · Closing up

Reassemble your wall clockGlass, bezel, clips, back panel

Disassembly in reverse, with one difference: this is the last time you will see the inside of the case, so everything gets checked before it is sealed. A fibre behind the glass or a hand that catches once an hour is a small thing now and a full strip-down later. Take the extra two minutes.

Before you start
  • Finish the alignment first. If the hands still need setting, run guide 03 before you close the case, not after.
  • Dry microfibre, and the screws you set aside. Nothing abrasive, nothing that sheds fibres, and a light you can angle across the glass.
  • Have the battery to hand. It goes back in before the glass, so you can prove the clock runs while you can still reach it.

  1. Clean the dial and the inside of the glass

    Go over the inner face of the glass with a dry microfibre, then tilt it under a light and look across the surface rather than straight at it. That is the only way to catch the fibres and dust you will otherwise be looking at for years. Work around the hands on the dial, never across them.

    Caution

    Keep solvent on the glass only. Alcohol on a printed dial can lift the printing and dull the luminous markers, and neither comes back. For a mark on the dial itself, a barely damp cloth and patience. Apply anything wet to the cloth, never into the case.

  2. Put the battery back and prove it runs

    Fit the battery and leave the clock running while you get the glass ready. Watch the second hand cross the twelve, the three, the six and the nine. Every fault in this archive shows itself in one revolution, and right now it costs you nothing to fix.

    Note

    If a hand hesitates or stops anywhere, go back to guide 02 before you go any further. This is the last moment you can reach the hands without undoing everything.


  3. Seat the glass in the frame

    Lower the glass into its slot and look at it from directly above. Anything less than square on and perspective will tell you it is seated when it is not. If your model has a cyclops, this is the moment to get it centred over the date window — once the bezel and clips are on, moving it means starting again.

  4. Fit the bezel, then flip the whole thing over

    Lay the bezel on and check two things before you move: the glass has not shifted in its slot, and the twelve on the bezel lines up with the twelve on the dial. Then hold the bezel and dial together as one and turn the clock face-down in a single movement.

    Caution

    Nothing is holding the stack together yet. Let go of either half mid-turn and the glass drops out. Grip both, turn once, set it down.

  5. Fit the clips, two at a time

    Put two clips on first, opposite each other, and stop. Turn the clock over and check the alignment through the glass. While only two are on there is still enough play to nudge the dial straight; once all four are seated there is none. When it looks right, fit the other two evenly spaced.

  6. Back panel on, screws in, done

    Set the back panel on the way it came off and check the hanging hole before the screws go anywhere near it. Fitted upside down, the clock will sit crooked on the wall and you will be back here to correct it. Then run the screws in, working across the panel rather than round it.

    Caution

    Finger-tight and no further. The threads are cut into the case, and leaning on the driver at the last quarter turn is what strips them.

Before it goes on the wall

Four things, one minute. Everything on this list is easy to correct now and a full strip-down to correct later.

  • The second hand completes a full revolution without hesitating anywhere.
  • Nothing behind the glass. Angle it under a light one last time.
  • The twelve on the bezel and the twelve on the dial agree.
  • If it has a date, it turns tonight at midnight rather than in the evening.
