Nivada Grenchen Autochron Blue 38mm Watch
Ref. 77003A45
Sits in Nivada Grenchen’s upper tier here — more premium than three quarters of the Nivada Grenchen watches we list, which start at £485.
Price range £485 to £2,310 across 48 Nivada Grenchen watches in stock.A compact 38mm case in brushed and polished 316L stainless steel, measuring 12.7mm thick without the crystal, gives this chronograph a manageable presence on the wrist. The double-domed sapphire crystal carries an anti-reflective coating, and beneath it sits a textured matte blue dial with two black sub-dials rendered in Jean Singer exotic typography. Printed Super-LumiNova indexes and a tachymeter scale complete the layout, alongside a framed date window at three o'clock. The bidirectional fluted rotating bezel features a black aluminium insert with a yellow dot at twelve, a detail drawn directly from the original prototype. Inside, the ETA Valjoux 7750 runs at 28,800vph with a 42-hour power reserve. A flat three-row stainless steel bracelet with a toolless micro-adjustable clasp finishes the watch, and the screw-down crown and solid caseback support 200 metres of water resistance.

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 200m it is rated for swimming, snorkelling and recreational 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 42 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
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 44.3mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
