Daniel Roth founded his eponymous brand in 1989 after 7 years at Audemars Piguet in Le Brassus and then at a very run down Breguet named company -- a shop in Paris.
The Chaumet brothers (jewelers) bought the name and wanted to restore glory to an old French name. Breguet as a company outsourced a few pocket watches each year for nostalgic collectors since they did not actually have manufacturing facilities.
After 14 years with the Chaumet brothers and "Breguet", Daniel Roth left when InvestCorp bought the brand.
He formed Daniel Roth brand and made his iconic watch shape known. Zurich investors pulled out in 1994 along with their distribution networks. Singapore-based watch retailers 'The Hour Glass' bought majority-holding and sold mainly in Asia. They sold the brand to Bulgari in 2000.
In the Hour Glass years 1994 - 2000, base movements were sourced from a variety of companies including Girard-Perregaux, Zenith (El Primero chronograph), Jaquet (moonphase), IWC cal 952 and others.
They were not expensive new watches after the Singapore 'discounts' so my only comment would be that any price that the re-seller is asking far exceeds the 'value'. On the other hand the 'value' in a used-market is the price a buyer is willing to part with.
