The SBGR305 was released in 2017 and limited to just 968 pieces. Cased in Seiko’s very own “brilliant” hard titanium, the watch measures 40.5mm in diameter and 13.6mm in thickness. The case is a mixture of polished and brushed surfaces perfected with Zaratsu polishing. The hands and markers, hand polished and razor sharp, are some of the finest found in any watch, period. The dial has an attractive sand like texture that reminds us of the vintage GS 5646-7040 (which we’ve sold numerous times).  Its subtle details, only apparent when the light catches it just right, is unmatched in Swiss watchmaking.


This Grand Seiko SBGR305 is in overall great condition. It is unpolished and is in near mint condition as the original owner rarely wore this watch. The watch was originally purchased in Ginza Wako and comes as a full set with its inner and outer boxes, certificate of guarantee and time testing certificate. It is in full working order and the watch is currently running at +5.6 seconds/day.
