According to horology blogs and vintage watch listings, Salvest watches were primarily produced during the mid-20th century, with some watches dated as far back as the 1950s. The brand name belonged to a German firm, Blessing Werke KG, which operated from 1940 to 1977. The name can also appear on Swiss-made timepieces. 
History of Salvest watches
The history of Salvest watches can be broken down into two distinct areas:
German-based clocks: The trade name Salvest was owned by Blessing Werke KG, a German company founded in 1940 and based in Waldkirch. The firm ceased operations in 1977. While known for stylish mid-century clocks, the company also produced wristwatches.
Swiss-made wristwatches: Some Salvest wristwatches have been explicitly noted as Swiss-made on vintage listings, such as a "17-Jewels Mechanical Movement" model and a "Swiss Hand-wind" model.
Mid-20th century production: Examples of Salvest watches found on vintage reseller sites suggest that the company was active throughout the mid-20th century. For instance, one model containing a Cattin C64 movement was dated to circa 1980, while another vintage ladies' watch was from the 1950s.
