Best looking diver’s true GMT for the money
A green watch in multiple ways. Solar quartz gives maximum accuracy with zero battery changes. Subtlety textured green dial surrounded by a green chapter ring and green bezel gives a great background for the orange pop of the GMT hand. The two tone chapter ring allows you to track the daylight hours for the GMT hand. This is a Flyer GMT and not a Caller GMT, so it is perfect for going diving on vacations far away from your home time zone. The sumo case is large and weighty, but as with most SEIKOs, it wears smaller and comfortably on the wrist. The bracelet’s center band sits slightly raised to give some dimensional interest. I would have expected a case this large to have a 22mm band, but this has a 20mm lug width. Looks good and still in proportion to show off the brushed and polished finishing on the stainless steel case. The date at 3 o’clock and the crown at 4 o’clock positions give it a distinguishing look. I love that it has a sapphire crystal for scratch resistance. The Prospex lines are well made, I own 5 (Turtle, Sumo, Samurai, Speedtimer, and PADI SNE549). The only knock on this watch is the aluminum bezel instead of a ceramic bezel upgrade. Some might have issue with the dive bezel marking instead of the 24 hour GMT bezel, but I respect the design choice that this is a dive watch first and foremost.

Stunning Seiko SSA423 Automatic watch Presage Collection
I bought the Seiko SSA423 Automatic Watch Presage Collection it is absolutely stunning, it is not that heavy on the wrist. I bought it May 25, 2025 and it came in at May 30, 2025. Although the watch needs resizing it was fairly easy. Probably if you have a very thin metal cylindrical tool you can push the link out then put it back with the instructional arrows pointing the direction of the link. Anyways I bought this watch as a beater watch which I will wear everyday I didn’t hesitate so you shouldn’t also. Retail value of $575.00 and bought it for $466.83.

Really good looking Seiko/ Honda collaboration.
Great looking watch. Seiko/Honda collaboration is a great combination. Brand new and looks good on the wrist. The NATO strap is hard nylon and not comfortable to me but it really complements that watch. The price was awesome too. The watch arrived on time and was brand new.

Seiko - Issues with current version
My first version of this watch lasted years. The latest order, date and day mechanism was broken out of box. Returned for replacement and same issue with replacement. Don’t know if bad batch but I went for an alternative brand.
