Titanium Perpetual Calendar Caliber 8F32, ca. 1999
Update April 28th 2009
A most strange thing happened in the night from the 28th to the 29th April: the Perpetual Calendar 8F32 jumped one day ahead. A possible reason could be that the nearby army radio station has sent some really strong signals, triggering the chip to jump one day ahead. However when thinking back to the time when I bought this watch in Tokyo in 1998, it might simply be that I got a lemon . Once I have measured the circuit, I will update this section. Right now my trust in the 8F32 movement is close to zero. It's really not what you want when putting on a perpetual calendar. Imagine you are traveling on a dense business schedule with time zone changes and then your perpetual calendar lets you down. Not a pleasant experience for sure.
The two rubber parts 4H37-BA 8 died on March 5th 2009 after more then 10
years of use
This gives it a life of 10 years and 2 months. Not bad rubber choice from SEIKO here. Although I have heard that people that wore their Perpetual Calendars often, saw these rubber parts deteriorate much earlier. I will update this page once I have found the replacement 4H37-BA rubber part that links with the watch case and the clasp. The Titanium braces on the side of the rubber reinforce the bracelet and are connected with two short spring bars each. A pretty complex combination. SEIKO certainly set a trend with this rubber Titanium combination back in 1999. It was a novelty indeed, to be followed by many brands. This combination seems to have been a JAPAN version only and was not for sale (officially) outside Japan. Makes me wonder how difficult it will be to get this part. We just returned from a skiing trip in Hokkaido on February 11th, 2009 and crossed Tokyo from Haneda to Narita in an airline limousine. That route passes the SEIKO headquarter in Tokyo too. Of course Murphy made sure I would find my rubber part broken right after that Japan trip...
Since the watch houses a 10 year CR 2412 cell and comes with a rather complicated resetting procedure, I have decided to stick the watch head to the wall in my smoking room. A little piece of Blu-Tack does the job. And of course I made sure that if the Blu-Tack softens or dries (this unfortunately happens in tropical climate), the watch will not fall to the ground. A WIS precaution ;)
Now my most accurate Quartz watch (no RC signals in Thailand) has become a wall clock. The battery did not make the promised 10 years, it was first replaced in June 2004 after 6 years of working. Now I am of course curious to see how long the second CR 2412 will last.
