Commemorative Coin Watch

The picture shows an unique commemorative coin watch
The watch was sold in Australia in the late 90s period.

Watch case was plated with 22k gold.

What is most valuable is the commemorative coin that was used for the dial.

The piece of real legal coin (was used as the watch dial) was minted in 1951 to commemorate the 50th anniversary of establishment of Australian Parliament (est. 1901).

The legal tender of the coin is one Florin which is equal to one Australian dollar at that time.

The coin's face was marked with the symbol of Parliament (crossed sword & sceptre), Stars of Australia and a British Crown at 12 o'clock. The word AUSTRALIA was displayed from 10 o'clock to 2 o'clock position. On the dial's left portion marked the year 1901 and on its right, 1951.

The coin was treated with silver coating before it was used for the watch.

I don't think there are many such pieces (coins) to be found.
