Push buttons unscrewed counterclockwise to the point where it is free of the screw threads. In this position ensure that the chronograph second hand is set at zero. Next, start the timing sequence by pressing the upper push button. Push the upper button again once the predetermined distance has been covered. The second hand comes to a halt indicating the average speed on the bezel. Screw down all push buttons tightly to make the watch pressure-proof once again.


Buying diamonds, some advice...

When buying diamonds people will usally ask about the C's - Cut, Colour, Clarity and Carat.

Most have done a little internet research and quickly come to the naive conclusion that they need a D colour diamond that's internally flawless before understanding how much this type of gemological perfection will cost. Its only then that the real search starts!

Most customers will usually say that they just don't understand diamonds or how grading works. Below is a good place to start but in my humble opinion the very best grader of a diamond is your own eyes and your own heart. If you love the diamond in front of you the gemological science isn't really that important as long as the price is right. After all, you don't sit at a dinner table showing your friends the certificate!

If the diamond you like is within budget, sparkles beautifully, looks a good colour and has plenty of "life" then what else could you possibly wish for?

"Life" means that the diamond should talk to you, sparkle nicely, should not look flat and should look clean to the eye. Some diamonds with a high grading have less "life" in them than some lower graded stones. That's why your own eyes are the best tool you can use. 

"Life" in a diamond is like a persons soul. It not something that you can really touch, but you can see it in their eyes. I hope that makes sense. If a diamond salesman is showing you a stone that has a great Certificate but no soul then that's no good to you. I repeat, you don't wear the certificate and no one is interested in what it says, only when you come to sell it... And even then, the diamonds "life" will be the main area of importance.

People around the World, but especially in the UK pay far too much importance to diamond certification. You should remember that a certificate is only the opinion of the person who issued it and another grader may see it completely differently. What's really important is how YOU see it...

FL = Flawless: No inclusions or blemishes are visible to a skilled grader using 10x magnification. Extremely rare, less than 1 in 5000 jewelry quality diamonds are rated FL.

IF = Internally Flawless: No inclusions, only blemishes are visible to a skilled grader using 10x magnification.
FL and IF diamonds appear identical unless viewed under 10x magnification by a skilled grader. Less than 3% of jewelry quality diamonds are rated IF.

VVS1 - VVS2 = Very, Very Slightly Included: Inclusions are difficult for a skilled grader to see under 10x magnification.
VVS1 inclusions are typically only visible from the pavilion, while VVS2 inclusions are visible from the crown. In each, the inclusions are invisible to the eye, appearing identical to the higher grades unless viewed under 10x magnification by a skilled grader.

VS1 - VS2 = Very Slightly Included: Inclusions are clearly visible under 10x magnification but can be characterized as minor.
Inclusions are not visible to the naked eye. Perhaps 1 in 100 untrained observers can detect VS2 inclusions with the naked eye, on close inspection under ideal conditions.

SI1 - SI2 = Slightly Included: Inclusions are noticeable to a skilled grader using 10x magnification. SI1 is the lowest grade with flaws often invisible to the naked eye. SI2 inclusions are usually visible to the naked eye, although they will require close inspection.

I1 - I2 - I3 = Included: Inclusions are obvious under 10x magnification and may affect transparency and brilliance. I1 diamonds have inclusions that are almost always visible to the naked eye.
Because I2-I3 diamonds have pronounced inclusions, and in the case of I3 may even affect the diamond's durability, I do not buy this quality diamond under any circumstances.
