    Precise electronic time-easuring device with selected, artificially aged, temperature-stabilized quartz. Manufactured and test according to the testing rules of the former German Hydrographic Institute (DHI), the current Federal Office for Navigation and Hydrography (BSH). The outstanding feature is the accuracy of the rate, which far exceeds the technical requirements stipulated by Part 2 of DIN 8319. Other superlative attributes of this precise instrument are excellemt legibility and the ability to change the battery without interrupting the running.
    Case dimension: 185x185x130mm
    Dial: 95mm diam., white with black Arabic numerals
    Movement: Stepping motor with 60º angular step, frequency 0.5 Hz. The second hand moves in successive jumps of 1 increment per second.
    Electronics:  MOS-IC´s and smi-conductrors on a printed wiring board 55x135mm, the entire electronic system is housed in the base of the chronometer´s case.
    Quartz: Frequency 4.194.304 Hz.
    Helium leakage rate: 1.10-11 Pa m3/s
    Operating temperature range: -5ºC to +50ºC
    Voltage:
    Batteries: 4 mono cells 1,5V IEC R20 or LR20
    Lifetime: 1year for alkali manganese batteries
    Accuracy: Average daily rate 0.01 sec./24h at 22ºC (-+1ºC)
    Security distance: The security distance to the magnetic compass is 0.90m
    Weight: 3.5 kg

    The chronometer passes before delivery a work shop test that fulfils DIN 8319 standard according to the requirments of the BSH in Hamburg formerly know as DHI.
