With the SeaQ Panorama Date, the Glashütte watchmakers have successfully adapted the Calibre 36 to meet the considerable challenges of timekeeping underwater.The promise of quality integral to the calibre is also kept by the SeaQ Panorama Date. This means not only that the watch meets the stringent DIN and ISO standards for diver’s watches, but that it must also undergo the same demanding 24-day excellence test.
Rigorous quality standards - Glashütte Original
Rigorous quality standards
The central requirement in developing the SeaQ and the SeaQ Panorama Date has been maximum reliability. As a consequence, the DIN and ISO certified diver’s watches meet the most rigorous German and international standards of quality, with a particular focus on water resistance.
ENTRY CONDENSATION TEST
Test for moisture in the watch
As a first step, the SeaQ is heated to 40-45°C for 30 minutes and then covered with a cold wet piece of felt. When no condensation appears on the inside of the glass, the watch is in conformance with the relevant standard and enters the testing phase.
MEASUREMENT OF AIR PRESSURE
Testing of resistance at underpressure and overpressure
The SeaQ is exposed first to an underpressure of -0.2 bar. The watch is then tested at an overpressure of 125%. For 20 bar watches this corresponds to a value of 25 bar, and for 30 bar watches to 37.5 bar.
WATER OVERPRESSURE TEST
Water resistance test
The watch is first exposed to an overpressure of 125%. For 20 bar watches this corresponds to a value of 25 bar, and for 30 bar watches to 37.5 bar. This overpressure is maintained for a certain period of time. It is then lowered in a second phase to a slight overpressure of 0.3 bar.
DRYING THE WATCH
Exterior drying of the SeaQ
Following the water resistance test in a water bath, the SeaQ is rotated under a curtain of air in order to dry the exterior.
FINAL CONDENSATION TEST
Test for moisture in the watch after testing
As a final step, the SeaQ is again heated to 40-45°C for 30 minutes. Once again a wet piece of felt is placed over the upper surface of the glass. If no condensation appears on the inner surface of the glass, the watch has successfully completed the testing phase.
