The 38-mm case of the Seiko SARB017 is made of stainless steel. The watch is moderately sized, measuring in at just under 13 mm thick and 46 mm lug to lug, and is thus a great unisex option. The top of the case is brushed, while the case sides and bezel are polished.
The SARB017 features a dark green sunburst dial with golden, applied hour markers that alternate between Arabic numerals and wedge-shaped indices. The edge of the dial hosts a printed minute track with luminous dots. The date window is housed at 3 o'clock. The design is rounded off with a golden bezel.
The timepiece has the cathedral hands often found on pilot's watches from the 1920s and 30s. They are golden and filled with luminous material.
This reference's special feature is the outermost ring of the dial, also known as the rehaut. Seiko chose to design it as a rotating ring with a compass scale. This inner rotating ring is operated via a second crown at 4 o'clock. The compass ring is used to determine the cardinal directions with the help of the time display and the position of the sun.
The watch is protected from the elements by an anti-reflective, scratch-resistant sapphire crystal. Seiko decided against a date magnifier for the SARB017, a feature that is present on the Red Alpinist from 1995.
In-House Caliber Seiko SARB017
Inside the stainless steel case, you'll find the Seiko automatic caliber 6R15. This movement offers a stop-seconds mechanism, manual winding option, and a 50-hour power reserve. The balance oscillates at a frequency of 21,600 vph.
