Setting Your Mimora: Time, Date, and Moon Phase
Every watch in the Debut Collection runs on a Sellita automatic movement, so worn daily it keeps itself wound and you rarely touch the crown. When a watch has been set aside, or when the date or moon phase needs correcting, the steps below bring it back. This guide covers each model in turn: winding by hand, the date, the moon phase, the time, and, on the Voyager, the chronograph. The procedures differ by caliber, so follow the section that matches your watch.
On all three, the crown pulls out in stages. Pushed home against the case it winds the mainspring. Pulled to its first stop it reaches the quick calendar correction; pulled fully out it sets the time. Every movement hacks: in the time-setting position the seconds hand stops, so you can release the crown on a reference signal and start the watch to the second. If your crown screws down, unscrew it before setting and screw it back down afterward.
Buena Vista
The Buena Vista carries the Sellita SW200-1, a self-winding movement of 26 jewels beating at 28,800 vibrations per hour (4 Hz), with a minimum power reserve of 38 hours. Its winding stem has three positions: running and manual winding, quick date correction, and time setting.
Wind. With the crown home against the case, turn it to wind the mainspring. A watch that has fully run down needs winding before it will keep time.
Set the date. Pull the crown out one stop to reach the quick date correction, then advance the date to the current day.
Set the time. Pull the crown fully out. The seconds hand stops. Set the hours and minutes, then push the crown home to restart the seconds on your reference.
Springtide
The Springtide carries the Sellita SW280-1, a self-winding movement of 26 jewels beating at 28,800 vibrations per hour (4 Hz), with a minimum power reserve of 38 hours. It adds an instantaneous moon phase alongside the date, and both are corrected from the same crown position. We recommend setting the moon phase first, then the date, then the time.
Wind. With the crown home, turn it to wind the mainspring.
Set the moon phase. Pull the crown out one stop. Turn it until the full moon sits in the middle of the moon-phase window. Find the date of the last full moon on a calendar that shows the moon phases, then advance the disc one jump for each day that has passed since that full moon.
Set the date. In the same position, quick-correct the date to the current day. This one stop carries both the date and the moon-phase corrections.
Set the time. Pull the crown fully out. The seconds hand stops. Set the hours and minutes, then push the crown home to restart the seconds on your reference.
Voyager
The Voyager carries the Sellita SW510 BH b, a self-winding chronograph movement of 27 jewels beating at 28,800 vibrations per hour (4 Hz), with a minimum power reserve of 56 hours. It shows the time with small seconds at nine o'clock and a chronograph, and it carries no date, so the intermediate crown position sets nothing on this model.
Wind. With the crown home, turn it to wind the mainspring.
Set the time. Pull the crown fully out. The small seconds at nine o'clock stop. Set the hours and minutes, then push the crown home to restart the seconds on your reference.
The chronograph is driven by two pushers. The pusher at two o'clock starts and stops the timing: press it once to begin, again to stop. While it runs, the central chronograph hand sweeps one full turn every sixty seconds. With the chronograph stopped, press the pusher at four o'clock to return the chronograph hands to zero.
The Voyager is rated to 30 m. Do not operate the pushers near water.
When a Watch Has Stopped
A watch left unworn past its power reserve will stop. Wind it by hand first, with the crown in its home position, then set the time and calendar, so the movement has the energy to run and to snap the display cleanly. Once set, wear it or keep it wound so it does not run down again. On the Springtide, check the moon phase after a long stop, since the disc advances only while the watch runs.
