Seiko Prospex Sea SRPC Date 42.3mm (Mini Turtle)

The Seiko Mini Turtle is the greatest watch I ever had the pleasure of owning. In fact, it is my favourite watch of all time, and one that will remain in my collection eternally.

The reasons I love it so much are, of course, all very subjective, but they could serve as a guide for your decision-making, were you to entertain the thought of buying this watch.

Let’s just start at how it looks. When it comes to monochrome watches, collectors like to reference the Rolex Submariner or Omega Speedmaster as a benchmark for the monochrome design, but for me personally, the Seiko Mini Turtle takes the whole cake. In fact, it probably took over the whole bakery and all the pastry and cream that is out there. It is so perfect-looking.

The sharp contrast between the creamy white indices and deep black dial is perfect in itself, but the way the indices and the handset are shaped really makes the experience special. And that small, round date magnifier glass ads a ton of class a "luxury" to the appearance of this watch, and that comes from a guy that hates date magnifiers. It just works perfectly on this Turtle.

There are heaps of Lumibrite on the hands and indices. Seiko is great at luming up their watches, and this generous amount of friendly-looking green lume is bound to put a smile on your face whenever you enter a poorly lit corner of this world. The bezel action is smooth and solid, and on my watch at least, it all lines up perfectly.

The dial is covered by a Hardlex crystal, which is annoying. It should be sapphire. And don’t give me the BS about Hardlex being less hardened so it takes more water pressure due to the elasticity, because I don’t care. If the Submariner is OK with sapphire, then Turtle will be perfectly fine with it. Besides, the greatest depth any of us will take our dive watches is no more frightening than a relaxing walk in a thin, melancholic but very comforting rainstorm.

The 4R movement is fine. It is automatic, it hand-winds, hacks, has a date, not very accurate but acceptable — it is, once again, fine.

Now, the key aspect of this glorious timepiece that I saved for last: the dimensions!
Oh my God, did Seiko nail the literally perfect sizing of a dive/sports watch! First of all, I love cushion cases as they wear incredibly comfortably due to clamping onto your wrists like a curious octopus trying to make new friends.

The case diameter is 42mm, which allows for a magnificent wrist presence and great legibility. The lug-to-lug distance, however, is 43mm, making the wearing experience of this unique watch feel like a 40, or dare I say, 39mm wristwatch. It is truly remarkable how this one wears.

Whenever you glance down at your wrist, you are presented with a solid, beefy, macho man–approved proper dive watch, but when you look in the mirror (to bathe in your sparkling beauty of presence, because it is very likely that you are indeed on the narcissism spectrum), you see a dude (or gal) rocking a modestly sized, quality-looking, instantly attractive wristwatch.

In my review of the OG Seiko Turtle (the 45mm beast), I wrote that I am convinced the designers of Seiko are utilizing black magic on a daily basis — otherwise, their watches could not be this comfortable — but with the Seiko Mini Turtle, I’m confident that they made a deal with Lucifer himself. The Mini Turtle (especially on an elastic parachute strap) is divinely comfortable.

I’ll mention the bracelet briefly, because you can get this watch supplied on the stainless steel, oyster-like bracelet. I never wear the bracelet as it feels too heavy for this watch, and it is just not appropriate in my opinion. The bracelet ruins the fun a bit, adding heft and unnecessary bulkiness to the watch.
It has solid links and end links; the latter separates from the bracelet once you take the spring bars out — that is not a very good feature. The clasp is pressed and it has an additional, but completely useless, diver’s extension, adding even more unnecessary bulk to the watch.
The links are held together with the cursed pin and collar system, the sizing of which cost me many of my cheap Chinese tools and a great portion of my mental well-being. And because I am the sort of person that can only barely survive without cursing as often as possible (especially when there is a great bit of frustration involved), I’ll just stop writing about the pin and collar before things get out of hand.

And to finish this review, as a last thought: value and prices.
The Mini Turtle is a very unique watch from Seiko’s catalogue and it is unfortunately discontinued, making prices on the used market increase into shamelessly bold territories.
The prices start from 300 EUR + shipping/tariffs/TAX/etc. on the rubber strap, and they go from there. I got mine on the bracelet, full box and papers, new old stock for 200 EUR. That is where the prices should be, but as the Hungarian saying goes: “Wishes are for the church only,” so enthusiasts have to stomach these prices. It is completely worth even overpaying a little, because once you have this watch on your wrist, you don’t really want to let go of it anymore.

So be warned: ownership of this watch will cause severe jealousy amongst your other watches, collecting dust in the watch box. There may eventually be an uprising within the neglected class of watches. Buyer be aware!
