Stepping up in Nivada Grenchen's range
The defining feature here is the sector dial — eight vertical indexes radiating outward to create the spider's leg motif that gives this watch its name. The silver sunray finish is paired with cream Super-LumiNova on both the hands and hour markers, and a date magnifier sits at the perimeter. The double-domed sapphire crystal carries an anti-reflective coating. The 316L stainless steel case combines brushed and polished surfaces, measuring 38mm across and 45mm lug to lug at 11.1mm thick. A screw-down crown provides 100 metres of water resistance. Power comes from the Soprod P024 automatic, with a 38-hour reserve. The beads-of-rice bracelet continues the vintage reference throughout.

Learn more about Nivada Grenchen
Nivada was founded in Grenchen in 1926 by Otto Wüllimann, Hermann Schindler and Jakob Schneider, registered as Wüllimann, Schneider, Nivada SA. It was among the first Swiss firms to build automatic watches at scale, and it built its reputation on watches meant to be used rather than admired.
American sales came through the Croton Watch Company, an arrangement forced by Movado, which objected to the phonetic similarity of the two names. This is why vintage examples turn up signed Croton, Nivada, or both, and why Grenchen was eventually appended to the name.
The Antarctic of 1950 was the brand's first water-resistant automatic, and it earned its name properly: the model was worn by personnel on the US Navy's Operation Deep Freeze expedition to the South Pole in 1955 and 1956. The Chronomaster Aviator Sea Diver followed, a chronograph that tried to be a pilot's watch, a diver and a regatta timer at once, and the Depthmaster reached 1,000 metres.
The quartz crisis ended it. Production in Solothurn closed in the late 1970s, the name changed hands repeatedly, and Nivada Grenchen effectively disappeared while its vintage watches quietly became collectable.
Guillaume Laidet and Rémi Chabrat bought the name and back catalogue in 2018 and relaunched with faithful reissues rather than reinventions — the Chronomaster in 2020, the Antarctic in 2021 — at prices aimed squarely at the microbrand buyer.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 38 hours fully wound — so it will usually stop if you leave it off overnight.
What size strap does it take?
20mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 45mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
