- The Grand Seiko revealed the most specific movement on the spirits ever achieved.
- These watches offer an accuracy of ± 20 seconds per year.
- The Grand Seiko is again inspired by its natural environment in its Japanese headquarters.
There is precision, and then there is what Great seiko I just removed in Geneva. Fresh Out of Watches & Wonders 2025, the new Spring Drive UFA SLGB001 and SLGB003 stole the spotlight with one of the most specific outings in the world.
New caliber of Grand Seiko 9RB2
Propelled by the brand's news 9RB2 caliberThese watches offer barely credible precision of ± 20 seconds per year. Not per day. Not per month. Per year. It is the most precise movement fueled by Lepring Never done, which means that you could wear it for twelve months in a row and extinguish yourself as much as you simply lose by fixing the time manually on your vintage submarine.
As with everything related to GS, the 9RB2 caliber embodies the lasting pursuit of the brand's precision, refining everything, of its quartz oscillator internally aged to a new temperature compensation system with the appearance that is measured and adjusts 540 times a day. There is even an usable regulatory switch; A first for Spring Drive which allows you to settle decades on the line.
Spring Drive de Grand Seiko remains a strange and magnificent hybrid: 90% mechanical, regulated by a quartz oscillator, but with all the emotion of a hand -built movement. No batteries. No external power. Just a merger quietly by humming gears, crystals and know-how. This is the kind of flex that doesn't need to explain it … something that has become a signature for Japanese watchmakers.
Grand Seiko SLGB003 & SLGB001
Visually, the new UFA models are classic Grand Seiko Evolution 9, offering net angles, polishing of the razor and perfect proportions. Size at 37 mm and only 11.4 mm thick, the SLGB003 titanium and the SLGB001 platinum wear smaller and lighter than you think.
Especially once the light catches these “Ice forest” dials that are inspired by the frosty trees near Shinshu. Depending on the angle, they spend silver with pale blue, reflecting the transient environment in which these spectacular watches are produced.
THE SLGB003 in titanium You will cost you about $ 16,300 Aud and land in Australian stores in June. THE SLGB001 platinum is a limited series of 80 pieces and clocks at $ 58,200 AUD – which also released in June. The two figures that feel, if not “negotiate”, then at least more logical when you take into account everything that beats under the hood.
