Care & Information for Divers Watches.

As previously mentioned an automatic divers watch is an exceptional and extremely well made piece of kit, built to last in all environments, and with a little additional care, will give many years of faithful service!

Firstly become familiar with adjusting the watches time and day / date settings , this is always better done in daytime and shouldn't be attempted between the hours of 9pm and 4am as this can sometimes lead to damage of the date change mechanism, to set the time and date correctly, the screw down crown (winder) should be unscrewed then gently pulled out to the first click position, the date or day date can now be set, this should be set to yesterday's day date, then the crown should be gently pulled out further to the second click position, the hands can now be wound forward going past the 12 o'clock date change position to now enable the correct date to be displayed and the time adjusted thereafter. This ensures the date change to be in correct sync with the time changing at midnight, and not mid day! The crown should then be gently pushed in back to the (hand winding position on some models) screw down position, and taking care not to cross thread when beginning, screwed down tight.

The strap or bracelet should be adjusted to a comfortable position on the wrist allowing full movement of your hand without adding any additional strain to the watch band, not too tight, as your wrist will swell, not to loose or the watch will slide down irritating the back of your hand.

Simple care of the exterior of your watch is recommended periodically, and this is best achieved by a simple scrub with a soft nail or tooth brush in lukewarm water and washing up liquid. You will be amazed at how much grime can get built up during everyday use for a few months, and be pleased by the now refreshed clean look of your watch! You can of course go further by polishing out light scratches with a metal polish like Solvo Autosol and a soft cloth, before washing, but personally we prefer the used look as it almost adds to the character of the watch!

It goes without saying that an automatic watch cannot match the accuracy of a quartz watch, but nonetheless it is an amazing piece of engineering, movements have been made with all variations and different frequencies VPH or BPH ( vibrations or beats per hour ) as they are known, which is the count of oscillations of the balance wheel ( equivalent of swings of a pendulum in a clock ) The popular watch balance wheels oscillate at 5, 6, 8, or 10 beats per second. This translates into 2.5, 3, 4, and 5 Hz respectively, or 18000, 21,600, 28,800, and 36,000 vph. In most watches there is a regulator lever on the balance spring which is used to adjust the rate of the watch known as regulation in order to adjust its timekeeping accuracy. So if we take a watch movement of 21600 vph, as used in the Seiko Diver's, the movement oscillates 518,400 times over the 86400 seconds that are in a single day! When you start multiplying up into weeks and months etc the figures are quite astonishing and an understanding of this true marvel of mechanical engineering excellence can be attained!

Accuracy is usually stated as + or - 30 seconds per day, but can be considerably better, and this can be quite dependant on the way the watch is worn, although the more fully wound the watch becomes through wearing, on some models the slower it actually runs! If as we recommend taken off at bedtime, after two or three weeks of initial settling in, you will get a good idea of its accuracy and this can be improved by what's known as variational positioning, when you rest your watch, if your watch is losing time then lay it flat when at rest. If your watch is gaining time slightly then rest it vertically with the crown facing down, if your watch is gaining more, rest it vertically with the crown facing up, this will become a habit that will help regulate your watch.

We have heard of movements running for 10 to even 15 years or more without needing a service or replacement parts, but generally there will come a time when your watch will require some maintenance. With an expensive watch this is an easy decision, you send it back to the manufacturer's service centre or take it to a qualified watch repairer to undertake the work. However with a cheaper tool watch of the type we sell, you have further options, you can of course have it serviced, or even replace the whole movement with a new one, or you can just retire your old watch and replace it with a new one! You could even sell your old watch needing a service to go towards the replacement cost! It will always retain a residual value because it's an Automatic Divers Watch! There are many watch enthusiasts that will take it on, and fix it up, or even customise it with modded bits! There isn't really that much difference between the costs of these options! This is the benefits of a watch of this type, and you could even learn how to service it yourself by watching some of the excellent videos on the internet on the subject, and visit the excellent watch threads forums and blogs for additional information and help.

We hope that this introductory information has been useful if you are new to automatic divers watches, and worth reading if you aren't! We are enthusiastic about this type of watch and would like people to gain something from visiting our site, we don't do any hard sell campaigns, but rather try to give you the information so you can make an informed decision and invite you to buy from us if you wish!
