SILVER PLATED souvenir TEASPOONS x 2=BUCHERER of SWITZERLAND=LUCERNE=ROLEX WATCHES PROMOTION SPOONS!

Bucherer started in the 1950’s with a non Rolex logo design that read Bucherer Watches Lucerne. It included the lion in the bowl of the spoon. Around the same time, they began giving out the first Rolex marked spoon as a promo when you purchased a watch. This spoon had the Rolex displayed in a cutout at the spoon top and also included the lion in the bowl as the signature Lucerne trademark.
They issued several variations with the Rose in the center of the handle in a narrow and a broad pattern and then the Swiss Cross in more current spoons.

The markings on the backs of the spoons indicate silver content.  B 100 12, this meant 100 grams of silver was used to plate 12 Normal size spoon spoons, or 8.33 grams of silver per spoon, since these are smaller, the amount of silver would be proportionally less.  CB69, if you look close with a loop you can see it is actually 6,9 for 6.9 grams of silver per full sized spoon.
