For sale is this very pretty, 14k solid gold watch key. It measures 1 3/4" long and weighs a hefty 5.6 grams. The head of the key is set with two faceted oval pink stones that are very light garnets. The key is in excellent condition, has a "touchmark" on bail and has been tested and is guaranteed to be at least 14k gold. No damage or repairs. The measurement of the square key opening is approximately 2mm, but I don't know what size watch it will wind.
