Do’s:-

- Do wash your Rolex periodically – plain soap, soft toothbrush and water will do just fine.- Do carry out the drying and cleaning process in the safety of your bed – not over bathroom tiles.

Murphy is just a handshake away.

- Do try to keep your Rolex away from strong magnetic fields.

- If you lay your watch on the dresser, do keep the dial away from direct sunlight. Over an extended

period of time, strong sunlight can fade away the dials.

- At night, do rest your watch on a soft padded cloth on your dresser. Avoid direct contact with another

piece of metal or wood.

- If you place your watch flat on its back, dial up, do place a cloth between the case back and the

bracelet.

- Do use Loctite 220 on the bracelet screws so that bracelet does not accidentally come off. There are

enough horror stories about people that have lost their watches because of loose screws. Rumor has it

that Rolex uses Loctite 220 as well.

- Do make sure that the crown is screwed in at all times.

- Do wear your Rolex as often as possible.

- Do get your Rolex serviced every 5 years. Hopefully from a certified Rolex watchmaker. We can help

- Do buy your Rolex from people that actually care about and understand Rolex watches. It’s generally a

fun hobby that has a tendency to turn into a good investment. Plan on spending your money wisely.

- Do remove your watch before playing Golf, Squash, or Tennis. Your ‘Train’ may get knocked out of sync.

Don’t’s:-

- Don’t use chemicals to clean your Rolex. It doesn’t matter how effective the chemicals are in cleaning

- Don’t use chemicals to clean your Rolex. It doesn’t matter how effective the chemicals are in cleaning - Don’t use chemicals to clean your Rolex. It doesn’t matter how effective the chemicals are in cleaning

- Don’t use chemicals to clean your Rolex. It doesn’t matter how effective the chemicals are in cleaning any other household dirt or grime.

- If you watch has stopped, don’t violently shake your watch. Nice and soft swirls, just like swirling a

fine red wine in a wine glass, to get the rotor moving will do the trick.

- Don’t over tighten the crown. You don’t need to. The seal inside the crown has been designed to sit on

top of the stem and form a perfect hermetic seal against the elements. The more you tighten it, the

greater the pressure exerted on the seal which will eventually break with the pressure against the top

of the steel stem… eventually losing its efficacy as a waterproof seal.

- Don’t worry about scratches on your Rolex. Scratches give it character.

- Don’t worry if you should or should not remove the hologram on the case back. Eventually, it will come

off.

- Don’t fret about your Rolex gaining or losing 2 seconds every month.

- Don’t open up the crown more times than necessary.

- Don’t use anything stronger than Loctite 220 to ensure that the bracelet screws stay in place.

- Don’t buy your Rolex from fleabay. Plan on spending your money wisely.

- Don’t polish the center links on SS watches to make them look like something they are not. It’s tacky,

please don’t do it.

- Don’t wear short-sleeve shirts in the middle of winter to show-off your Rolex. You’ll catch pneumonia.

Starting in 1987 Rolex started putting a letter in front of its serial numbers on each watch. The following is a list of letter and the year the watch series was introduced. Please note that it is not uncommon to find a mix of serial numbers mixed in. For example at my local Rolex AD here in Toronto they have Y, F and D serial watches available. What does this mean? Not much in terms of the watch itself other than the fact the the old serial number watches were probably made further back. They also may have had it sitting in their inventory for some time. This does not effect the Rolex factory warranty as it starts at the date you purchase the watch and not the date of manufacturing.

Rolex consistently adjusts their serial and model numbers to keep the tracking of models and years easier for collectors of Rolex watches.

Contrôle Officiel Suisse des Chronometers (COSC).
Founded in 1973 in its current structure, the COSC is a not-for-profit association. It was created by five watchmaking cantons (Bern, Geneva, Neuchâtel, Solothurn and Vaud) as well as the Federation of the Swiss Watch Industry. It encompasses the laboratories that had been established independently of each other from the late 19th century onwards.
Definition of a Chronometer
A chronometer (like a Rolex) is a high-precision watch capable of displaying the seconds and housing a movement that has been tested over several days, in different positions and at different temperatures, by an official neutral body (COSC).
Each chronometer is unique, identified by a number engraved on its movement and a certification number given by the COSC.
Each movement is individually tested for several consecutive days, in 5 positions and at 3 temperatures.
Each movement is individually measured. Any watch with the denomination “chronometer” is provided with a certified movement.
Methods
To our knowledge, the laboratories are the only ones in the world to apply this standard on an industrial scale. They deliver more than 1,000,000 official chronometer certificates per year. Nonetheless, this represents only 3% of Swiss watch production, a proportion that underscores the exceptional nature of a chronometer.
In doing so, they rigorously apply the testing conditions laid down by the norm.
It is vital to recall the fact that these tests bear absolutely no relation to a simulation of watch behavior and performance when worn.
These are static tests applied in laboratory conditions to movements and not to finished watches.
The results provide a “photographic” image of the rate of a movement at a given moment and certify its intrinsic position.
Nonetheless, due to their severity, these tests are highly selective and only extremely high-quality movements can hope to pass them.
This is therefore an examination based on excellence, even if the behaviour of the movements that are granted certification is still directly dependent on the wearers themselves.
To earn chronometer certification, a movement must be made from the highest-quality components. Also they must be object of special care on the part of the finest watchmakers and timers during assembly.
It is thus a product with extremely high value added and therefore stands out quite clearly from standard quality watch production.

Rolex is not only a great example of this level of watchmaking but stands out as the world’s premium brand.
