Notes

OctaBesides the unusual design of its dial, the "Octa" also incorporates a technical feast: a large and more stable balance with free-sprung balance spring to deliver chronometer precision performance over the full period of 120 hours. After this period the watch-if unwound-will still run for one or two days, but with timekeeping at a lower rate of precision due to the loss of amplitude until the mainspring is wound-up again. Power will be fully restored after only 3 hours of wearing the watch due ta highly efficient bi-directional winding system. This, in combination with an oversized and easy-to-read date makes the "Octa" an especially practical daily timepiece to wear. And of course, case, dial and movement are executed with impeccable finish and superb decoration.
