Long Term Assessment: The Modern Mariner - A Five‑Year Wearing Review of the Tudor Black Bay “Midnight Blue”

There are watches that impress at first sight—and then there are watches that endure. In a world where fleeting trends often masquerade as icons, the Tudor Black Bay “Midnight Blue” stands apart: a timepiece whose reputation grows not through novelty, but through lived experience. Over half a decade of wear, testing, travel, and everyday life, the Black Bay has evolved from an admired diver to an indispensable companion.

This is not a standard review. This is the story of what happens after the honeymoon period ends.

A Legacy Reborn

When Tudor revived the Black Bay line in 2012, it did more than reissue a vintage diver—it distilled a design language shaped across 60 years of Tudor’s underwater exploration. Its spiritual ancestor, the Tudor Oyster Prince Submariner ref. 7922 from 1954, lends DNA to the case, crown, and the clean, functional ethos of the watch.

Chromalight is Rolex's proprietary luminescent material that glows blue in the dark.

It's used on the watch's hands, hour markers, and sometimes the bezel pearl (e.g., on the Submariner) to ensure legibility in low-light or no-light conditions.

Head-To-Head: Seiko Alpinist SPB117J1 (6th Generation) versus Seiko Alpinist SARB017 (5th Generation)

The Alpinist is classic line of sports watches from Seiko. It is a series of watches designed in 1959 for mountain climbers. The first is the iconic Laurel Alpinist. The most famous of all the Alpinist and a cult classic, the SARB017 is the face of the series. This is the 5th generation Alpinist and it was launched in 2006. In 2020, Seiko launched the 6th generation Alpinist with updated movement. 

I have the SPB117J1 (below and left) and the SARB017 (below and right). In this short write-up, I will be comparing both watches.
