This Groundbreaking Omega Watch’s Accuracy Is Calibrated Using Sound

Omega has been making the Constellation for much than 70 years, a ticker that was the Swiss brand's elegant flagship timepiece earlier the Speedmaster landed successful 1957. It got its moniker from an representation connected its caseback—an observatory beneath 8 stars. The stars symbolized 2 chronometer records and six first-place precision awards that Omega earned betwixt 1933 and 1952, the twelvemonth the Constellation launched.

But Omega's caller Constellation Observatory postulation has a wholly caller process for measuring accuracy, 1 that gets astir the thorny contented of these pieces having nary seconds hand.

Why should a seconds manus matter? Watches are tested for accuracy with photographic tracking of the seconds manus implicit a play of time. Having nary seconds manus makes this impossible. The Constellation Observatory pieces, however, assistance Omega immoderate watchmaking past arsenic they are the archetypal two-hand watches to execute Master Chronometer certification without a seconds hand.

Traditional investigating by COSC—the Swiss assemblage that certifies the accuracy of Swiss watches—uses photographic tech to measurement the presumption of the hands successful antithetic positions and temperatures astatine regular intervals for 15 days. The accuracy modular is –4 to +6 seconds per day. COSC lone tests the movement, not the afloat watch. The case, bracelet, and magnetic absorption each autumn extracurricular the test, and for two-hand watches, a seconds manus has to beryllium added to bash the indispensable tests.

The much stringent METAS method tests the full finished watch, not conscionable the movement, taking into relationship however it performs with the lawsuit on, successful real-world conditions, with vulnerability to magnetism, somesthesia changes, and h2o resistance. To pass, a ticker indispensable beryllium close to wrong 0 to +5 seconds per day, and defy magnetic fields up to 15,000 gauss. For Omega's proprietary certification of Master Chronometer, a ticker indispensable walk some COSC and METAS testing.

So, however has Omega managed to grant the caller Constellation Observatory watches Master Chronometer presumption adjacent though nary successful the postulation person seconds hands? By devising an accuracy trial that doesn't request the photography oregon a seconds manus astatine all.

Omega's Laboratoire de Précision has fashioned a self-contained investigating portion that continuously captures the dependable of each tick and tock portion signaling biology parameters (temperature, position, and atmospheric pressure) passim 25 afloat days of testing. This is simply a sizeable betterment connected photographing the presumption of the seconds hand, capturing conscionable 2 information points per day, arsenic this caller strategy generates continuous information from the archetypal second.
