Yeah. High accuracy quartz ftw. I’m not in the market right now, but if I was, I’d buy your GS in a heartbeat. I miss my SBGR053 or whatever the reference was...
SBGR053 is a beauty. Funny enough, I think GS entry level is amazing value. The super expensive pieces are awesome too but anything in between is a bit imperfect... can’t deal with the “upside down” power reserve on most Spring Drive powered watches.
The GS is a quartz. No comparison :-)
Manufacturer says within 10s per year but it's more like 2-3s per year in reality. Quite remarkable I think.
