Thankfully Seiko is not throwing all their eggs in one basket. The have world class quartz with the Grand Seiko calibre good to +/- 10 secs per year. Not as good as the Citizen Chronomaster but damned impressive nevertheless.
Then they still make world class mechanicals in the Grand Seiko line and awesome ones a slight step below with the Brigtz line. Then the 6R15 is a sweet movement and I had two Sumos to get acquainted with this movement.
I am very glad to hear that a 6R15 based chronograph might be on the way! How many have asked for a spiritual successor to the 6138/9 chronographs of the 1970s? The Sumo gave us an "afforable" hacking and handwinding diver and the dress watches built on this movement are generally stunning.
Now that pesky Spring Drive. Time will tell how well my SD 600 will hold up. I am hopeful that it will go close to 10 years before needing service. If I can get there and another 5-10 years beyonf before the solid state stuff goes wonky I will be happy. So long as there are parts I will be happy
It is not quite 1/2 sec slow per WEEK!
Want to regulate my MM Randal? I would love to see how good this could run with the help of a master such as yourself. It drives me nuts that an essentially hand assembled watch with a Grand Seiko derived movement gives me such so-so accuracy and stability results. The watch itself is such a jewel but the timekeeping is simply not as good as the movement is capable of. Why doesn't Seiko charge $200 more and adjust the thing to 3 positions?
