Eska is one of the smallest watch brands. After the end of World War I many watch manufacturers appeared in Europe and Sylvan Kocher & Cie. was of them. The name Eska is the phonetic spelling in French of the letter s and k (es-ka). The wristwatches of the brand included manual and automatic models, besides models with full calendars and digital time displays.
Yacht timers are also known as yachting chronographs, sailing watchers or regatta timers and they were designed for the countdown before the start of a sailing race. The start of a regatta is quite different from a race on the ground: the sailboats are positioned before the starting buoy and when the gun goes off, the countdown begins and the competing boats cross the start line 15 minutes later. So, yacht timers are used on the countdown and they also denote the remaining time of the race.
