An earthy clay that is typically red and is native to Armenia but can also be found elsewhere is called Armenian bole, also known as bolus armenus or bole armoniac. Later, the term "Armenian" was used to describe a particular property of the clay. It was once employed as medicine, but it has since been put to use as a pigment, poliment, foundation for gilding, and for other things. The iron oxide that gives it its red colour is also present in the clay, which also has hydrous silicates of magnesium and potentially aluminium.
Historically, the term "bolu" or "bolus" was only applied to medicinal earths, and Armenian bole was astringent medicine used to treat bleeding, diarrhoea, and dysentery. Theophrastus, Dioscorides (c. 41-90 AD), and Pliny the Elder all mentioned Armenian bole (23–79 AD). It was applied externally to reinforce plasters to prevent joint dislocations. Because it is thought to be located in the city of Synope, doctors have sometimes referred to it as Rubrica Synopica. As the minerals frequently include poisonous heavy metals including arsenic, cadmium, lead, and zinc, use for internal medicine may have adverse effects.
It was added to non-soluble teeth powder in the nineteenth century. These powders would create an ugly stain by being lodged between the gums and the teeth. They were therefore painted crimson with Armenian bole to hide the accumulation around the teeth.
Moreover, it is used in bookbinding as a substrate for the gold leaf to add depth and lustre to the binding as well as for colouring or applying to the edges during gilding. It is utilised in ceramics as a red colour for Turkish znik pottery. In addition, it has been used to waterproof windmill sails. A common concoction was 10 litres of water, 0.75 litres of grease, 0.75 litres of linseed oil, and 1 kg of bolus.

The Hong Kong slowdown drove global Swiss watch exports down 10.7% to CHF 1.74 billion for the month. And reduced the growth of Swiss watch exports for the half-year to a crawl. Exports for the January to June period rose 1.4% to CHF 10.67 billion, according to FH data released last week. (Through May, exports were up 4.1% in value.)
As famously used in the George Daniels' Space Traveller pocket watches, and developed with a helping hand from his contemporary British watchmaker, the late Derek Pratt, the resulting escapement construction features separate but equal escape wheels, mainspring barrels, and gear trains, with a detent managing the impulses from the escape wheels to the balance.
Finally, the watches reach the last stop, where a group of watchmakers completes a full check of the watch and its functions, coordinates any request for engraving, and fit the bracelet or given strap. Interestingly, the engraving is laser-based and you can actually do some pretty wild designs...
