When it comes to servicing quartz movements, the most likely and cheapest route taken is to replace the movement. However, sometimes the parts for watches and movements are so rare and tough to find, that servicing is the only option. As was the case for this gorgeous Seiko Grand Quartz from the mid-seventies, the Seiko 4843A movement was not readily available and the need was there to take it apart and service.
