Baselworld 2018: Grand Seiko Celebrates the 20th Anniversary of Calibre 9S with Three New High-Beat Limited Edition Watches

By Jovan Krstevski

Grand Seiko celebrates its 20th anniversary with three special movements, a fresh case, and a unique dial. In 1998, GS introduced Calibre 9S which now powers most of GS watches. This movement was designed from scratch and made for high precision and durability. The new watches are ref. SBGH265, SBGH266, and SBGH267.

This model highlights the collection’s rarity and value. It’s limited to 20 pieces and uses 950 platinum for the case and the folding buckle. The dial is in a silvery-white color, with silver hours and minutes hands and a blued seconds hand. The case also features 2 surfaces of Zaratsu polishing that extend to the lugs. The back showcases the high-beat movement with the rotor decorated with a gold medallion.

The next model highlights the collection’s classical side. It takes on elegance and presents a predictable 39.5 mm case in 18k yellow gold with the same finishing as the first model. Interestingly it is also a limited edition of 150 pieces. Powering the watch is the same high-beat 5Hz movement but regulated to “normal” Grand Seiko standards, meaning a precision of +4 to –2 seconds per day.

The dial of the watch has a silvery-white color with the signature GS radial pattern and small GS mosaic. The hands and the indexes are made in yellow gold matching the case design. And just like the first model, the back presents the 9S85 movement adorned with a gold medallion that depicts the Grand Seiko lion emblem.

Finally, the third edition on offer for the 20th anniversary of the 9S movement marries the qualities of the first and second models with an added sportier design. This model is not limited and carries an affordable price tag. Here we see a stainless steel case with a dressy dimension of 39.5 mm. The dial features the same radial pattern in a cooler dark blue color with rhodium-plated hands and markers including the gilded seconds hand. The back also showcases the same high-beat Calibre 9S85 with an original rotor and same regulation to +4 to –2 seconds per day. For more info, visit Grand Seiko online.
