Seiko Turtle

The Turtle is an iconic diver’s watch made famous by the Apocalypse Now movie. From the ever popular range of Seiko dive watches this is the one with the smooth, cushion like case.

The history of Seiko Diver’s Watches goes back to 1965 with their very first model. From then on Seiko have lead the way in innovation, design technology, materials and style.

Seiko 6306-7001 – the original Turtle

In 1976 Seiko released the first of their “cushion cased” or “turtle shell” style diver’s watches. This popular range of dive watch is known as the “Turtle” because of it’s smooth rounded “turtle shell” cushion like case design. Initially released in 1976, the original Turtle (Seiko 6306 & 6309) was in production from 1976 until 1988. At that time both models were driven by an automatic (mechanical self wind) movement. Luckily for us – Seiko appreciated the potential popularity of the model and brought it back with a new 24 jewel Calibre 4R36 movement as shown below.

An original vintage 6306 Dive Watch sold on eBay

If you know what you’re looking for you can still get lucky on the auction sites. This lovely example of a used but running Seiko 6306 7001 – the original Turtle – was found on eBay by ChronoDivers. A watch like this with a solid provenance (possibly the original receipt / box / papers etc) could easily command £500 – £1,000. If you can find a model with the Scubapro logo on the dial expect to pay even more (but be careful to determine if it’s an original 7001 model or a later 6309-7040 version)

Scubapro 450 examples

Two examples of Seiko Turtle SCUBAPRO 450 found on eBay. The first is the original 6306-7001 model (probably circa 1976-78). This watch was, in our opinion, over-priced at £2,700 … at the time of publishing we are still watching it – no buyers. The other model is the later (early 1980’s) 6309-7040 version. For £500 you get an authentic vintage diver’s watch – this model was regulated and waterproof tested.

Old Turtle versus New Turtle

The main differences between the new Seiko Turtle watches and those from 1978 to 1988 (6306 / 6309) are as follows (2)

  • Case depth increased from 13mm to 14mm
  • Addition of a softer silicone strap (previously harder rubber)
  • The lollipop on the seconds hand was moved from head to tail
  • Seiko 6309 – 17 jewel automatic movement – non-winding non-hacking changed to Calibre 4R36 with 24 jewels with hand wind and seconds stop function.

What should you pay for a pre-owned Turtle

With their soft cushion shaped case these watches also featured a recessed crown at the 4 o’clock position and day / date indicators. The vintage 6306-7001 have increased significantly in value recently. A good clean, working, all original 6306 variant will sell for between £900 and £1,200. The very similar, still vintage in our opinion, Seiko 6309-7040 can be bought for between £400 and £750. A nice example of a modern pre-owned Save the Ocean SRPD21 can be bought for under £240

The example below is a modern era Seiko Prospex TurtleSave the Ocean“. This one has a “wave effect” embossed on the sea blue dial. Other versions can be found with a “Manta Ray” shadow sweeping the watch’s dial. The model here was sold £300 – not bad for a modern, accurate, 200m water resistant automatic self winding dive watch.

How about a Steeldive tribute to the Turtle

Customers who admire the general aesthetics of the Seiko Turtle dive watch may also like the Captain Willard homage watch by Steeldive UK. Not a fake – but a respectful and affordable tribute to a 1970’s classic diver’s watch as featured in the Apocalypse Now movie worn by Captain Willard (actor Martin Sheen). It was Martin Sheen’s character wearing the Seiko Turtle that has helped make it such an iconic divers watch.
