Seiko 5 Sports x Honda Super Cub III Automatic Blue Dial Blue NATO Strap Mens Watch SRPK37K1

The Case:

The Seiko 5 Sports x Honda Super Cub III SRPK37K1 features a 42mm stainless steel case with a brushed finish, enhancing its visual appeal. A distinctive touch is the blue unidirectional rotating crown with a 60-minute count-up scale, reminiscent of a fuel gauge. The unidirectional bezel’s grooved walls facilitate easy operation. Positioned at the 4 o’clock, the push-down crown boasts crown guards, safeguarding it from accidental displacement. Ensuring durability, the hardlex crystal exhibits scratch and shatter resistance.

The Dial:

The dial presents a multi-tonal blue design, boasting a simplified and easily legible layout. Large applied indices and a silver-framed handset contribute to its clarity. Both the indices and handset incorporate LumiBrite material, ensuring nighttime visibility. The chapter ring encompasses a white 60-second track, aiding precise timekeeping. Displayed at 3 o’clock, the date window features a silver frame. Notably, the Seiko logo is positioned below the 12 o’clock marker, while the “Super Cub” logo graces the 6 o’clock marker.

The Strap:

A blue textile NATO-style strap, adorned with Honda’s “Super Cub” typography, complements the watch’s identity. The strap secures around the wrist using a standard buckle crafted from black PVD stainless steel, ensuring both style and functionality.

The Functions:

Powering the watch is Seiko’s in-house automatic movement, the 4R36. This movement, known for its reliability, offers both self-winding and manual options and boasts an impressive 41-hour power reserve. With water resistance up to 100 metres, the watch proves suitable for various water-based activities such as swimming in shallow waters.

Free Strap Adjustment

It's important that your watch fits your wrist comfortably and looks great at the same time.

Leather strap watches tend to fit without a problem for most wearers. However, watches fitted with metal bracelets often need adjusting to get the perfect fit.

This is generally a very simple procedure. We can do this for you, or you can get the watch adjusted locally.

Option 1. Specify your wrist measurement and we will adjust it before being sent

When purchasing a watch which has a metal bracelet with adjustable links, we will gladly adjust the watch bracelet to fit your wrist before sending the watch to you - free of charge!

Simply type your wrist measurement (in inches or centimetres) into the bracelet size section of the checkout and we will ensure the watch bracelet is adjusted accordingly before being sent to you. We will include all the surplus links, with the watch.

How to measure your wrist

You can measure your wrist with a piece of string which you can measure against a ruler:

You should allow about half a centimetre (1/4 inch) of slack to prevent it being too tight on your wrist.

In the event of you needing an extra-long wrist bracelet, which requires an extension to the original watch, we must obtain extra links from the manufacturer, and in this event, we will contact you to inform you of any possible delays or applicable charges.

Watches with bracelets adjusted by WatchNation are still eligible under our refund policy.

Option 2. Buy the watch online from WatchNation and have it adjusted locally

If you wish, you can have it adjusted locally by another jeweller or key cutter. However, you will have to cover the cost of this option yourself.
