Watch glass replacement - Rado Watches

Getting a glass shouldn't be a problem, but as it sounds as though you intend to fix it yourself, then please be aware of the following.

It is essential to get the correct size glass - even 0.5mm difference in the diameter means either it won't fit or it's too small and falls out again. As you say that the glass is broken, I would be surprised if you could remove it and still determine the correct diameter.
You need to think not only about how to remove the broken glass, but also about how you are going to fix the replacement one. Many watches have a very fine plastic ring around the glass that holds it in place and this may have also been damaged.
Also, with many watches it's necessary to remove the back, crown and movement to effectively replace the glass.
If your watch has any sort of water-resistance rating then it would need to be retested afterwards.

Bearing all this in mind, I strongly advise you to take your watch to a reputable watch repairer and let them sort it out.
If the glass is anything other than round, then the cost tends to go up. Get an estimate from them first, and decide if what they will charge you is reasonable - if it isn't then spend the money on a new watch.

Hope this is helpful.

I assume you mean a Sekonda watch.
Watches from large scale manufacturers like Sekonda come with a wide range of glass sizes. 30mm diameter is a common one, but you would need to remove the glass in one piece to measure it. Watch glasses are commonly in 0.5mm steps (e.g. 30.0mm, 30.5mm,31.00 mm etc.) and may have rounded or bevelled edges so it is often very difficult to determine the exact size without removing the glass.
Additionally, there is the thickness of the glass to consider.
Finally, the 'glass' may be plastic, mineral glass or sapphire crystal.
All in all, you will have to know how to remove the back of the watch, how to remove the crown and stem in order to remove the movement, how to remove the glass in one piece, how to fit a replacement glass, how to refit the movement, how to refit the crown and stem and how to refit the back.
Alternatively, take it to a watch repair centre - you'll still have a working watch after they've finished with it.....

the video below has an example on how to replace the glass of a watch.

Many areas have places you can take the watch and have the glass replaced if you google search watch fixers in your area and google map them you should be able to find one close by.

I cant inform about the exact size of the watch glass by the model or number of the case. For that you need to use micrometer to measure the thickness and diameter of glass. Most sommon thickness is 1mm. If the glass is broke, measure the thickness of any broken leftover and then the diameter by puting the calliper arms into watches groove for glass.

mcdevito75 here, Look for a small watch repair shop in your area, for the replacement glass.

No problem with it. Any watch repair shop will order exact size glass for your watch and will fit it. Fitting is easy if you have special glass fitting press. No way to replace watch glass without this tool. Visit your nearest watch repair shop and ask for new glass. Rate me,plz.

I am not sure about prices in US, but over here in England we charge £15 - £25 for mineral glass (depending on size, thickness, e.t.c.) and £50 - £120 for sapphire glass. As for today: £1 = 1.60$. Doesn't matter how you name it - glass or crystal, both are right.
