Yes, Zenith watches are real bang for your bucks. Before that Italian [we shall not mention his name, may he be exiled forever] took over the top job in Zenith back in 2001/2002, an EP with SS bracelet could be had for RM6,900 at ADs. No need to negotiate. Nowadays, despite all the misadventure which nearly made Zenith a fashion brand like [name shall not be mentioned because may cause offense], an EP can still be purchased at the price below the 20K mark, also without much negotiation.
But like all watches, it's not going to be an investment unless it's THE Stratos FB actually wore during the jump and he has decided to present to you free.
