Caliber 9F 25th Anniversary Limited Edition: SBGT241
In celebration of this anniversary, the dial features several unique yet subtle details. At 5 o’clock, the original ‘GS9F’ monogram has been replaced with a special '9F25’ design inspired by the quartz symbol.
Just above the 6 o’clock position on the dial, a 5-pointed star can be found. This is a special designation reserved for watches of the highest accuracy – that is, watches with an annual variation of ±5 seconds.
