Setup and Initial Operation
Initial Winding
Your SEVENFRIDAY M1B/01 watch is equipped with an automatic mechanical movement (Miyota 8215). It is powered by the motion of your wrist. If the watch has stopped or has not been worn for an extended period, it requires initial winding.
- Ensure the crown is in position 1 (fully pushed in).
- Turn the crown clockwise approximately 30-40 times. This will provide sufficient power reserve to start the watch.
- The watch will begin to run as soon as it has enough power.
Setting the Time
- Pull the crown out to position 2 (the outermost position).
- Turn the crown clockwise or counter-clockwise to set the desired time. Observe the hour and minute indicators on the dial.
- Once the time is set, push the crown back into position 1 (fully pushed in) to engage the movement and ensure water resistance.

Operating Your Watch
Automatic Movement
The Miyota 8215 automatic movement in your SEVENFRIDAY M1B/01 watch is self-winding. As you wear the watch, the rotor inside moves, winding the mainspring and storing energy. A fully wound watch has a power reserve of approximately 40 hours. If the watch is not worn for an extended period, it will stop and require manual winding as described in the "Initial Winding" section.
Reading the Dial
The M1B/01 features a distinctive dial design:
- Hours: Indicated by the large disc on the left side of the dial, marked with numbers like 10, 11, 12, 1.
- Minutes: Indicated by the central hand, pointing to the minute track around the dial's periphery, marked in 15-minute intervals (0, 15, 30, 45, 60).
- Seconds: A small rotating disc, typically located near the 4 o'clock position, indicates the running seconds.
- 24-Hour Indicator: A small disc, often near the 9 o'clock position, provides a 24-hour indication.

Maintenance and Care
Cleaning
To maintain the appearance of your watch:
- Wipe the case and crystal with a soft, dry, lint-free cloth.
- For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.
- Clean the blue leather strap with a dry cloth. Avoid excessive moisture, which can damage the leather.
Water Resistance (30M)
Your SEVENFRIDAY M1B/01 watch has a water resistance rating of 30 meters (3 ATM). This means it is suitable for everyday use and can withstand splashes or brief immersion in water.
- Do NOT operate the crown while the watch is wet or submerged.
- Do NOT use for swimming, showering, bathing, or diving.
- Always ensure the crown is fully pushed in to maintain water resistance.
Storage and Handling
- Store your watch in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid exposing the watch to strong magnetic fields, which can affect the accuracy of the mechanical movement.
- Protect the watch from impacts and drops.
Service
For optimal performance, it is recommended to have your mechanical watch serviced by an authorized SEVENFRIDAY service center every 3-5 years. This includes cleaning, lubrication, and adjustment of the movement.
Troubleshooting
- Watch not running: If the watch has stopped, manually wind it by turning the crown clockwise 30-40 times while it is in position 1. If it still does not start, ensure it has been worn sufficiently to allow the automatic movement to wind.
- Time inaccuracy: Minor variations in accuracy are normal for mechanical watches. If the watch is consistently gaining or losing significant time, it may require adjustment by a professional watchmaker. Avoid exposing the watch to strong magnetic fields.
- Condensation under crystal: If you notice condensation inside the watch, this indicates a breach in water resistance. Immediately take the watch to an authorized service center to prevent further damage to the movement.
