Just a status of my HAQ collection, including visits to the Service center fro the DS 2 Chrono Titanium and the Longines VHP:
Citizen Chronomaster AQ4020-54Y (Tosa Washi paper): After uninterrupted 15 weeks (from January 2019) the the accuracy is 6.5 spy.
I do not think I will send this to Seiya-san, just for so little a difference (knowing the bad experiences I and others had with Citizen Service Center). During Mars, I worn it as specified by Citizen: every day, around 12 hours a day, without showing any significant change on the stated accuracy. At least, it is less than 10 spy
DS 2 Chrono Titanium: 7 weeks after repair (movement change), the accuracy is an excellent 3.92 spy.
What not to love: Independent hour hand for timezone change and daylight saving adjustment, extremely light (titanium), and offering a chronograph. Two weeks ago I started wearing it everyday, 12 hours a day, but as before, not significant changes in accuracy.
DS 2 Chrono Reverse Panda: I love reverse panda watches, and this one was just $ 300. 6 week ago I pulled a little too hard the crown so I stopped the second hand, and should start to measure again. Since that moment, the watch shows an accuracy of 9.25 spy.
Just at the limit of the specified accuracy by Certina, so nothing to complain. Of course, I would like it to be as good as my Titanium. I have not tried to wear it every day yet, but it may behave like the Titanium and not chose any big difference.
Longines V.H.P 41mm: After 6 weeks, ti is doing 4.13 spy.
Also, near the stated specification but, this time it is 5 instead of 10, so not bad at all. I have not tried yet to wear it every day, perhaps there will be improvements.
Well that is it for now. The Swatch service center has been very efficient and has increase my confidence on a correct repair, in case any of my Swatch Group watches is in trouble.
Thanks and regards,
