Is the Seiko SSK035K1 a true GMT watch?

Yes, it has a caller GMT (office GMT) movement where the 24-hour hand is set independently, while the main hour hand jumps for date changes. This is useful for tracking a second time zone.

What is the water resistance of the SSK035K1?

It is rated to 100 meters (10 bar), suitable for swimming and snorkeling but not for scuba diving.

Does the SSK035K1 have a sapphire crystal?

No, it uses Seiko's Hardlex crystal, which is more scratch-resistant than mineral glass but less so than sapphire.

What is the movement and power reserve?

It uses the Seiko 4R34 automatic movement with a power reserve of approximately 41 hours.

Is the bracelet easy to adjust?

The five-piece link bracelet requires a tool for sizing and does not have quick-release pins, so adjustment is best done by a jeweler or with a spring bar tool.

How does the SSK035K1 compare to the Seiko SKX007?

The SSK035 adds a GMT function and a more refined bracelet, but both share similar case dimensions and Hardlex crystals. The SKX007 has a screw-down crown and 200 m water resistance, while the SSK035 has 100 m and no screw-down crown.

About the Seiko 5 Sports SKX GMT Automatic SSK035K1

The Seiko 5 Sports SKX GMT SSK035K1 is a men's automatic watch with a round green dial and a GMT function for tracking a second time zone. The design takes inspiration from an archive Seiko deep green colorway. The case and bracelet are stainless steel, and water resistance is 100 meters.

The 24-hour rotating bezel is two-toned with a black upper half and is coated in Hardlex. A gold-colored GMT hand, high-visibility hour markers and the 24-hour bezel make it easy to read multiple time zones at a glance. The hands and indices are coated in LumiBrite, a luminous paint that absorbs light and glows in the dark, then fades slowly.

The "beads of rice" bracelet keeps the SKX look, with a five-piece link design that forms small X-shaped patterns. The watch carries the five original Seiko 5 features: automatic movement, day-date display, water resistance, recessed crown, and a durable case and bracelet.
