Tag Heuer 980.023 / 180.023 / 180.123 Review

Heuer (subsequently Tag Heuer) made some amazing dive watches. This review focuses on the dive watch which was in production for nearly 20 years in different variations and is known as ‘Deep Dive’ or ‘Spirotechnique’. This is certainly not the first post about this topic and definitely not the last.

Basic information

The watch comes either automatic or quartz, with depth rating of 1000m or 200m and under various brand names. The distinctive features of the watch are its large bezel and crown at 4’o’clock.

The most famous incarnation of the watch is the variant known as ‘Spirotechnique’. This is a watch initially produced by Tag Heuer and later produced by Auricoste for the diving equipment company La Spirotechnique. This watch was issued to Marine Nationale combat divers and the issued watches are the most sought after pieces especially if they come with provenance such as decomissioning paperwork.

The other pieces don’t share the same fame, but have other merits. The other variants come either Tag Heuer or Heuer branded. ‘Deep Dive’ variant 980.023 boasts depth rating up to 1000m. The automatic version 180.023 has depth rating of only 200m can also have the Spirotechnique logo on dial. The ‘Nightdiver’, or reference 180.123 has full tritium dial, but is otherwise the same as the 200m automatic.

The Dial

The dials of the different watches are nearly identical. They differ in branding, movement and whether it was produced for La Spirotechnique or not. The Deep Dive dial has a crystal retaining ring and extra gaskets which explains the extra depth rating.

All of the dials have tritium hands and indexes and no radium or luminova variants exist. I haven’t owned or handled the Heuer variant, but I wouldn’t hesitate adding one to my collection if one showed up.

The Movement

The ref 180.023 & 180.123 automatic versions use ETA2824, which is offers no surprises either positively or negatively.

The older Heuer branded quartz versions (980.023) use ESA movement, which can be difficult to source parts for in case of movement failure. However, the newer Tage Heuer branded ETA variants are replaceable quite easily and there are no worries from the maintenance perspective.

The Case

The case has uniformly polished finish and there is no play between polished / brushed surfaces. The bezel is a dominating feature of the watch as it is both big and tall. Despite of the polished surfaces, the watch pulls off that rugged tool-watch appearance that is very popular among vintage collectors today.

In spite of the relatively modern (read large) size, the watch wears comfortably. This is due to moderate lug to lug and low 12mm profile. My personal preference is a tall case back that extends bellow lugs and the non-Heuer variants lack this feature. However, it wears exceptionally well on nearly any strap or bracelet.

The edges of the lugs aren’t particularly defined, and the case is vulnerable to extensive polish. The crown side has two distinct surfaces and over polished cases typically loose the definition here. Same applies to the lugs, which also should have two distinctive edges diving the lug. On badly polished examples the lugs are nearly round and the definition is lost.

Polished case

Finally, the various references seem to have come with different crowns. Some of the 980.023N and 980.023L seem to have a smaller Tag branded crown whereas the crowns on the automatics seem to be larger. It may also be the watches I have handled have had service or aftermarket crowns.

The Bracelet

The standard bracelet to the watch is your typical Heuer / Tag Heuer diver jubilee with hollow end links. It is a comfortable bracelet, made out of good steel and a good companion to the watch. It is relatively hard to find these bracelets or extra links to them. Collectors looking to add add the bracelet to a rogue watch-head should be prepared to spend a pretty penny and significant amount of time on auction sites.

This is not going to be a popular opinion: the bracelet is is nothing special, and similar quality jubilee bracelets can be easily acquired if one suffers from the steel bracelet fetish and does not care about the originality. The bracelet is flimsy and rattly, but not in the good Rolex five-digit way. Both the deep dive and the Nightdiver are extremely versatile on a Nato strap and not being able to find a watch on the bracelet shouldn’t force anyone to skip the watch.


The Tag Heuer ‘Deep Dive’ or ‘Spirotechnique’ is a watch that works well on a nato strap. It is a versatile watch with very utilitarian look. It is susceptible to excessive polishing, but its maintainability is relatively good due to aftermarket parts producers such as tag1000diver. Even the ESA quartzes can be converted to more modern movements with some difficulty. As such, it is a vintage watch that can be worn, even heavily, which cannot be said from all vintage watches.

Blushark Orca Review


In the past few years, we have seen the introduction a few new Nato strap styles such as Tudor knit straps, Omega seatbelt straps, Marine Nationale stretch straps and perlon straps. Compared to a standard Canvas NATO strap, these new strap styles are a little different and aim to provide better comfort, slimmer profile, better adjustment and more colours and textures.

Omega and Tudor straps are also quite expensive. The general sentiment is that these straps are high quality and built by manufacturers with access to manufacturing facilities and materials unavailable to smalltime producers. However, one might think there is only so much you can do with a fabric and there must be a point of diminishing returns somewhere.

In simplest terms, Nato strap is a piece of cloth that is used to tie a wrist watch to your wrist. The point of the whole thing is that a Nato strap is cheap and disposable, and once the strap is worn out, you chuck it and buy another. Things I expect from a Nato strap:

  • Strong
  • Cheap
  • Not made out of too fancy or weak material
  • Lasts a long time.
  • Fabric doesn’t undo.
  • Steel hardware.
  • Looks good.
  • Enough colours.

Blushark Orca

Blushark Orca is a heavy-duty strap. Its distinctive feature is the waffle weave that sets it apart from basic canvas straps. The strap is thick, so you don’t perhaps want to wear your 1,7cm thick Planet Ocean GMT on one. However, for the thickness, you get excellent looks and a thick durable strap that seems like it’ll last a lifetime.

I’ve worn my Seiko Turtle SRP777 on one, and it works just fine. While the SRP777 is not particularly high, its still 14mm. For smaller watches such as skin divers and military watches the strap is perfect. It wears comfortably and the extra thickness doesn’t bother at all. The waffle pattern is different enough and the conservative colors create a very desirable rugged look.


The available colors are fairly limited, but yet enough. Colors that particularly work well with the Orca waffle strap are: army green, khaki, navy blue and gray. In addition to these the strap is available in the both standard ‘Bond’ colors, but I don’t participate in secret agent LARPs so I never wear those.

Three Orcas and two Phoenix Natos

In addition to the standard conservative colors of Blushark also offers some brighter colors. Of these, my favourite is the gray and orange and bright orange. The gray and orange works exceptionally well with titanium / bead blasted finishes. A colour that is on my wish list is burgundy or wine red. I’d definitely wear it with my watches with red details such as red seconds hand or red text.

Price & Packaging

Individually, the price of the Blushark straps is somewhat steep at 19 USD (checked in August 2020). However, Blushark runs ‘buy 2 get 1’ and ‘buy 3 get 5’ offers, which radically change the value proposition. This coupled with free shipping and -20% after a special offer such as holiday or sale and you have nearly unbeatable price per strap a little over 10 USD a piece.

The single biggest disappointment with the Blusharp Orca strap is the packaging. Each strap comes individually packaged in a plastic foil. This is quite literally, total waste. The strap could come either in thin paper or — surprise surprise: no packaging at all. This may be difficult to implement as obsessed strap enthusiasts will return the products when encountering the slightest scuff on the hardware.


Whereas the recent trend has been copying Omega and Tudor straps, the waffle weave Orca is a reminder what a strap should be. With the price of single Omega strap, you can buy 20 Blushark straps. Blushark offers a serious good looking Nato strap for a decent price that definitely works well with tool watches.
