It is time to change the battery on my Grand Seiko SBGN003 GMT with the 9F86 quartz movement. In this video I give you a look inside the watch at the beautiful quartz movement, but I don't go into explaining my tools or process, so if you have any questions please post them in the comments below.

First time I think I ever saw someone use gasket grease after changing a battery on a Youtube vid. Depending on how old the watch is I try and use a new gasket if i have the size on hand.

Features​

The first Grand Seiko 9F quartz GMT model. The perfect caliber for the international traveler.​

Caliber 9F, which was developed to create the ultimate quartz watch, now features the GMT function for the first time. This new addition to the Grand Seiko Sport Collection allows you to fully enjoy the newly-designed Caliber9F86 in a genuinely sporty design with the sophisticated thinness that is unique to quartz watches.
The watch allows you to move the hands without stopping the watch when setting it to local time. This achieves a convenience in which excellent accuracy of the quartz watch won’t be lost.
The case features a simple three-dimensional, thin design, which creates a comfortable fit. By featuring a screw-lock crown, the watch maintains excellent airtightness and water resistance as well as durability.
The contrast created by the striking GMT hand and the upper and lower two-toned dial rings helps you intuitively tell whether the time indicated by the GMT hand is day or night.
