DIAL: The SKX175 dial looks a bit grey or very dark blue and many Seiko fans have theories on the color. What's most important is the dial is legible and the hour markers are circular, and there is a triangle at the 12 o'clock position. There is an equal spacing between the hour markers and there is a day and date function replacing the 4 o'clock marker. The day can be set in English or Spanish. The hour hand is sword shaped and the minute marker is an arrow. Best of both worlds.
CRYSTAL:Hardex which is a mineral crystal. Hardex isn't scratch proof, but it is more resistant to being shattered than Sapphire crystal, and worthy of handling scuba expeditions.
BEZEL: Made of steel like all other parts. The bezel rotates 60 clicks, meaning you can time in small increments, up to 60 seconds. The bezel has silver numerals.
CASEBACK: This diver has a tsunami design in the middle of the case back. and rare marking Mov't Singapore The movement looks easy to access through the six indentations around the movement to open it. The back is made of the same steel and brushed as well.
CASE:Seiko divers have a very distinct case that is unlike most diver watches. The new watches are circular with the crown near 4 oclock with crown guards. The size of the watch is 42mm in diameter which is inline with watches by today's standards. The case is made 316L stainless steel with brushed front and sides. The case is beefy and if you were to use a thin nato strap, it would look disproportionate.
LUME:Seiko divers are known for their bright lume and the SKX173 is no exception. The lume is on the hour markers, hands, and a few positions on the bezel. We've tested the lume, and the Seiko lume was much stronger and brighter. Seiko uses it`s own Luminova-style paint, called Lumibrite.
CROWN: Seiko diver's crowns are on the 4 o`clock position. This is guarded by crown guards and it's a screw-down. The screw-down is very tight and perfect for under water use as it's tough to shake loose. The crown controls the day, date, and time and if you go backwards the second-hand will also go backwards if you want to set the exact time. The crown is unsigned.
MOVEMENT: Seiko divers run on the workhorse 7S26 movement. This is one of the most reliable movements that Seiko makes. This is an automatic movement which requires physical movement. Once this movement gets going, it'll move at 21,600 BPH. There are 21 jewels in this movement which are used in areas where metal wear will occur and the jewels help to minimize this and keep the movement running at top speed. In one week of constant use, we noticed +/-10 seconds. This movement requires servicing every few years. The power reserve wasn't great at a little over 1 day, but otherwise, think workhorse, but make sure you move.
OVERALL: The Seiko Diver SKX175 029 is a durable workhorse. The case is hefty and carries some weight, but the dial and bezel are beautiful and legible. If you're going for a dressy look, go with the metal band, and if you're looking to actually use the bezel and dive with this, the rubber band is best. You're not going to find a better and more respected diver or just plain watch in the market. Do yourself a favor and find a watch band that fits your style
