Thanks, all 大大 here.
This is my 2nd Springdive. I am happy with my 1st one- the SBGA003. ![]() I have searched this 1st Springdrive (SBWA001/SMK001J) for more than 1 year. This is sure a collectable item because of it's a milestone in horology and its limited number. The quality of the case and bracelet is not comparable to the GS and it just feels like a US200 Seiko. The second hand runs smoothly without any jerky motion like mechanical watches. The power-reserve is only 48 hours comparing to the 72 hours in the the recent automatic Springdrive. After 48 hours, it is +0sec. This is a history of the Springdrive: The first generation Springdrive model should be launched in 1999 - branded under Seiko and was manual with power-reserve only 48h . Model no. SBWA001 (in Japan)/SMK001J (in HK). It is said to be a limited edition of 500 pieces. The gold version is SBWA002, 300 pieces. ![]() (pic from J Gauch's data base) This caliber (7R68) or its modification was continued to be used by Credor. The 2nd generation was launched in 2004 under Grand Seiko (caliber 9R65/9R66), automatic with power-reserve 72 hours. They are only sold in Japan and Taiwan. 9R65 ![]() 9R66 ![]() (pic from Seiko Japan) The models launched in 2005 under the brand Seiko are sold outside Japan (caliber 5R65/5R64): 5R65: Diameter 30mm, thickness 5.1mm, 30 jewels, 276 components and power reserve 72 hours ![]() (pic from TZ) 5R64: Diameter 30mm, thickness 5.8mm, 32 jewels, 280 components and power reserve 72 hours ![]() (pic from TZ) They are also automatic models. I do try to find out the difference between the 9R65 and the 5R65 but failed. Their specifications look similar: 72h power-reserve and accuracy 15s/month. I think they are the same except that the 9R65 is having better decoration. But I may be wrong! The models launched in 2006 are having GMT (5R66) and Moonphase (5R67, limited edition of 200). 5R66: Diameter 30mm, thickness 5.8mm, 30 jewels, 296 components and power reserve 72 hours ![]() (pic from TZ) 5R67: Diameter 30mm, thickness 6mm, 30 jewels, 288 components and power reserve 72 hours ![]() ![]() (pic from TZ) Cheers. chiukh2007 |

It is not a quartz nor an automatic. It is a hybrid. Fpr how Springdrive work, please read this detail article in Timezone: http://www.timezone.com/library/rdnotebook/200509073623 Since my Springdrives have not been repaired or serviced, I don't know how much it will need. Cheers. |
