This model has the 9F62 caliber, but has special specifications increased to +/- 5 seconds difference per year. At the 6:00 position, there is the stars mark of five angles to symbolize the high accuracy of 5 seconds years difference. Because the watch is still in production, the final product may look different than the current photo.
On Jan. 31st, Seiko announced the release of a new limited edition with the 9F Quartz movement. Not only does this piece commemorate the 100th anniversary of Seiko’s 1st wristwatch, it also commemorates the 20 year anniversary of the 9F Quartz. The SBGX103 is a new, very special, limited edition of only 2,000 pieces.
The SBGX103 has a specially selected Quartz crystal, and all 2,000 pieces have the even higher accuracy rating of only +/- 5 seconds a year deviation (as compared to +/- 10 sec a year as with standard 9F). Some of the other attributes include an 18kt yellow gold Grand Seiko lion medallion on the case back along with engraved serial number “XXXX/2,000″ and “Caliber 9F 20th Anniversary Since 1993″. The dial itself is also quite unique. It is embossed with a pattern to resemble “XX” (Roman numerals for 20) and small subtle GS lions throughout. At the 20 minute index, you may notice that the lion is backwards compared to the rest. This is also to signify the 20 year anniversary. The final icing on the cake is the gold star above the 6 o’clock to indicate its special accuracy rating. You may also notice this is not the typical oyster type bracelet you will generally see on the SBGX series. This model will have the zaratsu polished attributes you will find on other GS.
