Building a Grand Seiko SBGM221 GMT SeikoMod

Hi, im a hobbyist in Malaysia, i design and build keyboards, and watches too

This is a GMT watch with a 4th GMT hand instead of just a rotating bezel. This is based on the Grand Seiko SBGM221 GMT, but instead uses an off-the-shelf GMT movement - Seiko NH34. This movement is still relatively new, released back in August of 2022. It has a 4th pinion for a GMT hand on top of the standard NH35 date movement.

Cream dial with brushed hands and a blue gmt hand

This case has a domed crystal

I will receive a very small kickback at no extra cost to you, using my link helps support me building more watches for these videos. Thank you!
