Ah, I see you meant the face cover, my mistake.

The cover of a watch's face, known as the crystal, is designed to protect the dial. There are three main types of crystal found in watches: acrylic, mineral and sapphire.

Acrylic crystal is an inexpensive plastic that does not prevent scratches, but allows scratches to be buffed out.

Mineral crystal is glass, which is composed of several elements that aid in resisting scratches (it is seven times harder than acrylic crystal). It is generally found on more expensive watches.

Sapphire crystal is the cover of choice for premium watches. It is the most expensive type of crystal and is three times harder than mineral crystal. It is made of an extremely durable synthetic material that makes it shatterproof and scratch resistant (not scratchproof). Some have a non-reflective film to prevent glare.

I have an old clock about 100 years old that belonged to my great grandfather.
Specially made for him with the engraving "Kronometer Gustav Frich".

Sounds really interesting although I'm not really into old clocks.

I fear for the survival of our species.

Peace on earth.

Never fear, I predict that after the
species gets through the next choke
point, the next kind of humans may
do things better.....

I wanted to build one these precision clocks but couldn't come at the AU$8,000 price tag. Also my house vibrates from traffic so there is nowhere suitable to put one so it would function correctly. I was very tempted though so to have a reference clock for setting all my watches accurately.

I love the old grandfathers, especially those Westminster chimes

I've always wanted a grandfather clock. There was a children's show called Capt. Kangaroo, and one of the "characters" was called Grandfather Clock.

While we're on the subject of watches... I wear my dad's. It's a self-winding watch, and shows day and date. Love analogue time pieces.

And didn't that clock always go 'cookoo, cookoo'? I could swear it did, but then its been a long time since then.

I've come to like my digital Casio G-shock watches with day,date, month, pm indicator,utc time to help with the timezone confusion on these boards and alarms to remind me to watch Charmed and Jag and timers for cooking.

In North America we get clock updates via radio from the US NIST reference clock in Colorado. Like Chris, I have one radio set clock in the house, and set all the others off of it.

Yep, NIST, an Atomic clock...

We dont have an atomic clock transmitter in or near Oz. This is a shame because I have a couple of G-shocks from Japan with multiband 6 function.

Hope your wrong Vic. Let's wait and see.
