Water Resistance

  1. My watch is waterproof, right?

    No, most modern watches are water-resistant.  The pressure stated on the case or with the instruction manual is usually misleading.  A 30m water resistant watch is no more than splash-proof, the watch is tested at 30 meters in conditions without movement and therefore no variable pressure.  Your power shower would almost certainly destroy a 30m water resistant watch.


    A 50m watch will take more punishment but I still would not recommend swimming with it on.


    100m is a fair level of protection but if your watch does not have a screw-down crown (button) then it is a risk to swim frequently with it on.  If you do use your watch in water, get it checked every year.  Do not operate crown or buttons while the watch is wet and remember, leather straps will deteriorate 3 times more quickly if they get wet.

Time-keeping

  1. Why does my cheap watch keep better time than my expensive watch?

    A cheap Quartz watch will keep better time than a mechanical Rolex because a quartz crystal resonates exceptially fast and is very stable.  A mechanical watch is subject to many other factors that affect time-keeping, magnetism, heat and cold, the position the watch is in, the amount of wind that the mainspring has, the age of the watch and the condition of the oils as well as the quality of workmanship.


    Modern quartz watches resonate at 32,768 Hertz compared to, say, a new Rolex that resonates at 4!  A Rolex will typically keep time to 6 seconds per day when well maintained, that is an accuracy of 99.9930556%

Servicing

  1. What do you mean service my watch?

    As you can see from the pictures here, the watch is fully dismantled, cleaned in a machine with 3 stages; a solvent and 2 rinses then dried.  The watch is examined for and wear or damage and defective parts are replaced or repaired.  The watch is assembled and oiled using the recommended oils (I have 16 different oils and grease on my bench), tested on a timing machine for correct amplitude of the balance, time-keeping rate, beat-error, stability of the balance in different positions etc.  Then the case and bracelet get stripped down to be polished and grained back to factory finish, then ultrasonically cleaned, new seals, crown, pushers and glass get replaced where necessary and tested for water resistance.  The watch is set to the correct time and date and tested over a period of 4-7 days, depending on the watch, under different conditions before being returned to the customer.

how long to service my watch?

  1. Why does it take so long to fix my watch?

    I usually turn around a repair in 2 weeks, there are factors that will lengthen that period such as locating parts, if there is to be a delay, I will inform you as soon as I know.  I require a week testing an automatic watch so the repair itself doesn't take that long but as soon as I need a part then I am at the mercy of that company and the postal service of whatever country the part comes from.


    Some companies here in the UK are taking 16 weeks to service a watch, I don't have the answer to their delays.

Cost of repairs

  1. How are you cheaper than other companies? Are you cutting corners?

    No, I am a small company with few overheads.  No Managing Directors, Administrators or cleaners etc..  Just me...thats how I can be £200 cheaper on the likes of a Rolex Daytona service.
