We have all popular watch batteries in stock. We carry Energizer and Swiss Renata brand watch batteries. Cases are resealed when possible and pressure tested upon request. We will replace any battery in any watch unless the cell is no longer available, we have not yet found any watch brand that we couldn’t replace the battery in.

Batteries are generally only 5.00 – 6.00, and gaskets / re-sealing and testing usually do not exceed 35.00.

D I Y battery replacements usually end up causing costly repairs so save yourself the trouble and come see us.

Batteries are guaranteed for one full year.
15ATM pressure testing available.

Checking the balance

Checking the balance

    To check the balance for truth in the flat mount the balance in truing calipers.  To check flat swing blade over the rim of the balance and while slowly turning the balance observe the line of light between the balance rim and the blade, if there is any deviation in the thickness of the light line you will need to adjust the balance.  Adjust the balance by bending it with your fingers and a balance truing tool which is a lever with notches cut in it’s ends that you can slide over the balance rim or arm giving you leverage and an accurate way to manipulate the balance.

    To check the balance for truth in the round follow the instructions above but slide the blade to the side of the balance rim instead of over the top.  Adjust the balance in the same manner as described above.

See the illustrations below

Poising the balance

    To check the balance for poise means you check to see if it is heavier on one side than the other.  The poise of the balance is very important,  you will not be able to time the movement to positions other than dial up or dial down if the balance is out of poise.  To poise the balance you must first make sure the balance pivots are straight, polished and clean, Now make sure the poising tool is clean and level then set the balance on the poising tool so that only the pivots are resting in the blades of the tool, next take you hand away and let the balance roll freely, when it stops take note of the place on the balance that is farthest down and rotate the balance so that point is on top, then let go of the balance again and if it stops with the place you noted in the same spot as before the balance is probably heavier at that point and needs to be adjusted however it is always a good idea to check this several times until you are absolutely sure before you proceed.  To poise the balance you need to take weight away from the heavy point on the balance, you can do this in several different ways but the method I use and find quite satisfactory is to remove weight from the back of the screw where it can’t be seen.  I you a screw undercutting tool which only removes material from the inner portion of the back of the screw and leaves the rest of the screw intact, this leaves no marks to be seen from the outside and the balance is left looking untouched.  There are other tools that can be used that take material away from the head of the screw, I know of two tools that do this, one of which takes the material away from the outer edge by chamfering it and the other bores a small hole in the center of the head of the screw.  One method I do not recommend is filling the heads of the screws down, this method leaves the balance looking hacked and is in my opinion the sign of poor workmanship.  Solid balances without screws can be poised by drilling them, usually on the underside of the rim.

    When poising the balance remove only very small amounts of material at a time or you will be chasing it around the balance for ever.  And remember every bit of weight you remove from the balance will directly affect the rate.  Before you start removing weight check to see if any of the screws are loose or missing, check the balance arms to be sure they are not bent, make sure the balance is absolutely clean, check the pivots to be sure they are not bent and also check to see if someone has put a timing washer on only one side of the wheel, any of these things are easy to repair by themselves but if you don’t see them in the beginning you will just be compounding the problem.  You can also add weight by using timing washers but as with taking weight away adding weight also affects the rate.  If you suspect that one of the screws is not right for the balance, try finding the proper one, even the lightest timing washer will add a surprising amount of weight.  Poising a balance is a fairly simple operation when the proper care is taken.

Removing the movement from the case

Removing the movement from the case

To remove the movement from the case you will first need to remove the bezel then remove any case screws or clamps.  Then let the movement come out into your hand.  For some watches, particularly pocket watches  the movement comes out the dial side. For watches with one piece cases the movement comes out the dial side also.

Removing motion work

Removing motion work

 

    The motion work consists of the hour wheel which caries the hour hand, the cannon pinion which caries the minute hand and works like a clutch that slips on the center shaft and allows the hands to be set.  The minute wheel slips on a shaft that is staked into the lower plate, the minute wheel meshes with the cannon pinion and its meshes with the hour wheel.  The cannon pinion is friction fitted to the center shaft.  The hour wheel slides onto the cannon pinion.  The set wheel is usually under the set bridge and meshes with the minute wheel and the clutch wheel.

    To remove the motion work you first pull of the hour wheel, then remove the set lever bridge bridge screws, remove the yoke spring, remove the yoke, remove the clutch wheel and the winding pinion, then remove the set wheel and the minute wheel, then pull the cannon pinion using a cannon pinion puller or sturdy tweezers.

    Also most watches use a dial washer between the hour wheel and dial to hold the hour wheel down.

 

 

  Some watches have hollow center shafts through which another shaft is friction fitted. The cannon pinion is then staked onto the end of the shaft that is friction fitted through the center shaft.

Removing the hands

Removing the hands

 

    To remove the hands you must first be sure there is no dirt or broken glass on the dial that will cause scratches so brush the dial lightly with a soft dial brush and blow off the loose particles with a blower.  Line up the hands at 12, place a piece of paper or plastic with a V cut in it under the hands to protect the dial and use hand pullers or hand lifting levers to remove the hands.

Removing the dial

Removing the dial

 

    To remove loosen the dial screws located around the perimeter of the movement and carefully pull the dial off the movement. 

    Some movements use sliding levers,  for slide type ( found mostly on ETA movements ) use tweezers or a small screwdriver to slide the levers out and away from the dial feet.

    Some movements have screws located on the plate side with small notches cut in them that when turned lock against the dial feet.  To disengage loosen the screws until the notch lines up with the foot.

   Some older movements use pins that go through the dial foot, for this type simply pull the pins out and the dial will be loose.

   Some movements use only friction to hold the dial on the movement. (mostly quartz movements)

Letting mainspring down

Letting mainspring down

 

 

    To let the mainspring down safely you must disengage the click from the crown wheel while holding the crown.  First turn the crown clockwise just until the click releases and becomes free, then use a fine pointed object to hold click free from the crown wheel and let the power run down slowly using your fingers as a break on the crown to keep from releasing the power too fast.

    This takes some practice, if the power is released all at once damage to the barrel, wheels, pinions or mainspring could result.

    For watches with one piece cases where the movement comes out the dial side and the case has no removable back you will not be able to get at the back of the movement.  For this type of watch you must grasp the crown firmly and pull it out.  Or use plastic or soft brass tweezers to get behind the crown and pop it off.  These watches have two piece stems that have male and female ends that snap together.  Then remove the bezel and let the movement come out into your hands.  Then remove the hands and the dial and put the movement face down into a movement holder.  You will then need to use a pin-vise to grip the stem and then let the power down as described above using the pin-vise like you would the crown.
