Megaquartz 2.4MHz, P4 Prototype

As seen in the parent section and in the description of the P3 prototype, the development of the commercial 2.4MHz movement had demanded scientific research reaching the limits of physics and a considerable amount of time and money.

The final result was worth the efforts, as the finally issued ‘2.4MHz Marine Chronometer’ model is still the most precise, non – thermocompensated wristwatch ever made.

The first 2.4MHz prototypes running with cal.: 1500 were big and unpractical. As for the development of the quartz wrist watch in general, the main task was to miniaturise the components and optimise the battery size/life to be able to produce a wearable wrist watch.

Megaquartz 2.4MHz, P4 Prototype, 1971

Prototype category: functional, aesthetic

Description: Symmetric, truncated pyramid shaped, stainless steel cased prototype with brushed surfaces. Stainless steel, brushed, curved case back fixed with four screws to the case. Outside and Inside unmarked. Dial made of grey-blue anodised metal with white printed ‘Constellation’ at ’12’ and ‘OMEGA Megaquartz 2.4MHz’ above ‘6’. Metal, baton hour markers, white printed minute marks. Date window at ‘6’, red plastic date wheel. Metal hands, hour and minute hands highlighted in white, all white second hand. Crown with company logo at ‘9’. TSA button below crown.

Dimensions: 36 mm (without crown), lug – lug: 47mm, lug width: 20mm

Movement: Cal.: 1510 prototype, #00003828

Additional info: This prototype has been manufactured in very limited numbers and allegedly given to employees for functional testing. The movements of these prototypes remain very close to the marketed version.

More information about the development of these movements can be found in the parent section.
