The ADDIESDIVE MY-H3-2 enthralls watch enthusiasts worldwide with its robust case craftsmanship, uncompromising everyday reliability, and iconic maritime design.

However, even the most precise quartz movement eventually requires fresh energy when the second hand stops. To save a trip to the watchmaker and confidently handle the maintenance of your timepiece yourself, all you need is the right preparation. In this editorial service guide, we show you step by step how to replace your watch's high-energy cell in an absolutely material-friendly, safe, and professional manner.

Step-by-Step Guide for Movement Overhaul

1. 1
   Professionally loosen the case back Position the case opener precisely into the notches of the solid stainless steel case back. Turn the tool counter-clockwise with even, gentle pressure until the threaded case back can be completely loosened and removed.
2. 2
   Securing the case gasket Carefully remove the white rubber ring (O-ring), which ensures the watch's phenomenal water resistance, with tweezers. Directly check it for cracks or porosity.
3. 3
   Removing the spent watch cell Gently lift the small, delicate metal tab (retaining spring) next to the battery. The old battery will now release from its anchorage and can be removed.
4. 4
   Inserting the new power cell & sealing Insert the new quality battery exactly into the holder and gently snap the metal plate into place. Reposition the rubber ring absolutely flat on the designated rebate. Screw the case back clockwise until hand-tight to restore the protective seal.

With these skilled maneuvers, your ADDIESDIVE MY-H3-2 will shine in its accustomed mechanical perfection and be ready for the next years full of adventures above and below water.
