Nivada Grenchen Depthmaster; believed to date from the early 1960s.
In the late 1950s almost all watch companies made divers’ watches, following the success of the Rolex Submariner. However most of them were pretty much clones of the original Submariner with tonneau shaped cases, metal bracelets and black bezels. As far as I know, the Depthmaster from Nivada Grenchen was the only dive watch from this period that shunned the Submariner look.
If anything it looks like a small Panerai, but I doubt if the design is really a copy as the Panerai was not exactly a well-known watch in 1950s Switzerland. The case is numbered 57024.
It is a heavy solid steel cushion shaped watch with a gorgeous black dial, milled solid steel bezel engraved with indices for the first 15 minutes and numerals for the other quarter hour markers. The indices on the bezel are filled with black enamel and the bezel rotates in both directions. The dial features huge arabic even luminous numerals and luminous bars for the odd numerals. The hands are also luminous and in this aspect they do follow the Rolex line as they are Mercedes style; they are steel whilst the sweep seconds hand is painted red. The red seconds hand matches the 1000 on the dial, which is also in red. I do not know if the 1000 refer to the capabilities of the watch in feet or meters or if it is just a model number.
The movement is the ETA calibre 2472 with 25 jewels, automatic and jewelled to the center.
One of the more unusual aspects of the watch is that the strap bars are solid steel and screw into the solid lugs giving a much more secure attachment than is possible with spring bars, and (of course) as used by Panerai.
Dial is 95% case is 85% whilst the movement is 90+%.
Diameter 38mm; Lug to Lug 48mm; Height 4mm., it takes an 18mm strap and a new black leather one is fitted.
