3. Crown Stem Adjustment: If necessary, adjust the crown stem length to fit the new movement by carefully measuring, cutting, and filing the stem to size.

4. Movement Swap and Assembly: Install the new movement within the case, paying close attention to dial, hand, and crown alignment. Reassemble your Seiko watch, ensuring all components are secure.

5. Timing and Adjustment: Test the accuracy of your upgraded movement and make any necessary timing adjustments according to the manufacturer’s specifications.
