In addition to a 35SQ re-release I would expect related Grand Seiko 9F models with a similar case design but made from different materials and new dial designs with Grand Seiko branding to be announced. The recently released 9F86 GMT movement provides the ability to independently adjust the hour hand and can be regulated to ±5 seconds per year so this movement design may form the basis of any new 9F caliber. A new accurate non-date version with independent hour hand for the 35SQ reissue and and range of other new models with ±5 seconds, independent hour hand and a perpetual calendar function. I would love to see Seiko release an updated movement with increased accuracy and functionality as a real statement of their leadership in quartz technology. This year Citizen announced the prototype caliber 0100 to commemorate the companies 100th Anniversary that was rated at ☑ second per year.Ĭitizen has publicly stated that this technology will find its way into production models in 2019, so I would expect announcements at Baselworld from them. After more than five years, and erratic wear patterns, the watch was running fast by just 18 seconds. I have a Chronomater A660 based watch and find it to have excellent performance. The Citizen A660 movement used in some of their Chronomaster models is rated at an annual ±5 seconds, has an independently adjustable hour hand so you do not have to reset the watch when adjusting for travel or DST, and a perpetual calendar.


Seiko first issued a movement rated at ±5 seconds per year in 1978 with the release of the caliber 9983A in the QGA010. While highly unlikely it would be fantastic if Seiko use this opportunity to release an updated 9F movement with increased accuracy and functionality. The 9F movement should hopefully just be a simple three handed movement with no additional complications and I would expect this to be rated at ±5 seconds per year. Hopefully the case finish will be the same as the original model as the 2000 reissue had a different texture. I would expect a 2019 reissue to be configured with a solid 18K gold case and 9F movement.
