Citizen Super Jet Auto Dater Parawater 150m SADS 51202 Y 1967

This is an earlier version of Citizen diver Citizen Super Jet Auto Dater Parawater 150m AUDS 51202 Y. This model number of SADS 51202 has a close relationship to the SADS-52801 unibody divers (with the additional outer bezel) both watches are with 39 jewels).  

The Citizen Super Jet Auto Dater Parawater 150m reference SADS 51202-Y is a rare 1966 vintage diver from Japan’s early automatic era (without the usual outer black diving bezel).

Key Specifications
This model features a robust monobloc stainless steel case measuring 37.5mm across with nice 20mm lugs.  It houses the iconic Caliber 1150 or 1161 “Jet” automatic movement with 39 jewels, hand-winding capability, and quick-set date via crown pull.  Rated for 150m water resistance (Para 150m), it includes luminous trapezoidal markers, black dial, and a unique geared rotor design. 

Collectibility and Value
Priced around $850-1000 USD on secondary markets, its unibody “X-case” design and high jewel count appeal to vintage enthusiasts.  Servicing requires crystal removal due to the sealed back, preserving dive-ready integrity.

Lemania Series III Royal Navy Nuclear Submarine Non-Lume Chronograph (year 1964)

For 2026, my key collecting focus shall be on Quality then quantities of watches with a clear focus on filling the missing gaps in my military watch collections and diver watches. 

The Lemania company specialised in the production of chronographs (watches with a built-in stopwatch function). Chronographs are inherently complicated things to manufacture and for this reason, many watch companies brought in movements from specialists like Lemania. They supplied, amongst others, Omega (the movement that powered the first watch on the moon was made by Lemania), and luxury brands Vacheron Constantin and Patek Philippe. Because Lemania often supplied movements to other brands (for which they were uncredited), watches which are signed by Lemania are especially prized.

Lemania has also supplied chronographs watches for the Royal Navy for use by pilots and navigators in the late 1940s and Lemania continued supplying them until the early 1960s. 

I have been eyeing on this extremely rare single-button Lemania chronograph for several years. What makes this watch particularly rare and distinctive is that this Lemania watch was one that was delivered to the navy use during the mid-1960s to coincide with the commissioning of the United Kingdom's first nuclear submarine. The quantities of these watches are so few that not many people actually know the uniqueness and rarity. I can tell by the number of likes received from Xiao Hong Shu ( little red book ) from China as not many people knows about these niche watches.

The first British nuclear-powered submarine was commissioned in 1963; at that time the Royal Navy was using Lemania chronographs which had been issued from 1945 onwards, starting with the Series 1 and 2 watches with a round case until 1955, and then the Series 3 with an asymmetric case from 1957 until 1970.  

To meet the new need for non-luminous watches a number of existing Lemanias were converted from lumed versions (which generally had a black dial) by fitting a white un-lumed dial and non-luminous black metal hands.  The NSN was then re-marked by crossing out the 3306 and marking 3312 above it. These very rare and special watches were issued to crew of the Royal Navy’s nuclear submarines from the early 1960s until around 1990.




The general shape of these watches evolved over time to become asymmetrical (in order to protect the push piece), but the movements remained almost identical in their construction. This one here is part of the third series of military mono-pushers delivered to the British military and it looks a little different to the others. 

These Nuclear Submariner’s chronographs were produced in very small numbers and are one of the most highly sought after of all military watches. The single button operates the chronograph (stop-watch function) - the button in turn starts, stops and resets the chronograph. There is an elapsed minute counter, which allows for timing intervals up to 30 minutes.



For safety reasons, the radiation levels onboard nuclear submarines needed to be constantly monitored. Consequently, no luminous material was applied to the dial and hands of these chronographs so as not to affect the readings of the onboard radiation monitoring equipment.

Other than the absence of any luminous material, the Lemania Series III chronographs issued to crew of the Royal Navy’s nuclear fleet were essentially the same as those issued to pilots of the Fleet Air Arm.

The Lemania Series III differs from its earlier predecessors Series 2 in that it features an asymmetrical case with an integrated crown and pusher and is powered by a rhodium-plated shock-resistant version of the 15CHT known as the calibre 2220.

The vast majority of the Lemania Series III watches issued to the Royal Navy were assigned the NATO stock number 0552/924-3306. However, and as can be seen with  the watches issued to nuclear submarine crew had the last four digits replaced with the number “3312”, which refers to the dial and hands being non-luminous.

Sadly, the Lemania watch company is no longer in existence as it has been bought by Breguet in 1992. So the Lemania watch brands has become something of a cult brand in recent years and its watches are very much cherished by collectors. 


The case back has the original military markings: 0552/924 is the stores code for a chronograph wristwatch, 3306 denotes a black, luminous dial. This is stuck out and re-engraved with 3312 which is the code for the Nuclear Submariner’s chronograph with no luminous compound and a white dial. The number below, 80xxx is the unique identifier for this particular watch. The nuclear submarine fleet was small and so obviously the overall issue was small too. These watches would only have been issued to those whose job on-board involved making timing observations. It is believed only a few hundred Lemania Series III Non-Lume Chronographs were ever issued and good original examples are very rare and seldom offered for sale.






Please visit a very detail write up below :






I have tried to goggle and search for the Lemanai Series 3 onlines and the Issued watches number ranges from 768, 5243,4838xx, 800XX, 80022, 80062, 80202, 80135, 80331, 80582. 80683, 81201, 81202, 81212, 81215, 81234, 81385, 81437, 81952. There are not many of these around.

Citizen 150m diver Crystal Date, AUDS 52802-Y (year 1968)

I have always love the early Japanese diver watches such as the Seiko 6217-8000/1 "62MAS", Seiko 6125-7000, 6159-7000, 6105-8000/9 (C shape case), 6105-8110 Captain Willard, 61597070 Grandfather Tuna). Of the early Seiko diver watches, I have managed to keep the 3 key representatives. 

Following the New Year break, I have realized that I have not a single Citizen diver watch and I have decided to search for them.  During my search, The Crystal Date Diver reference AUDS 52802-Y from 1968 caught my attention. At 40mm, these watches are beautifully built and they are in fact quite hard to find. They incorporate a thick mineral crystal and lume that seems to age a lot better than the Seiko during the period.  

This is an early, perhaps second generations, 150m Citizen diver watch Crystal Date, AUDS 52802-Y (there is other models with OR-O). It was made in 1968. The hands are different then the rest of Citizen's divers watches because there is no “Mercedes” style hour hand. The Citizen Crystal Date reference AUDS 52802-Y is a vintage diver watch from Citizen’s early professional lineup.

The first model 150m diver has a simple looking crown  and a unibody. Starting with this second 150M model, the top part of the case has now a circular brushed finish and the unibody case was dropped and replaced with a screw back case. In addition, the Jet movement was replaced with a centrally mounted swinging weight movement (i.e. the Citizen automatic caliber 5410) and it has a very nice case back design.

Key Specifications
It uses a 40mm stainless steel case with 18mm lugs, featuring a multi-faceted design and special signed caseback.  Powered by the 33-jewel Caliber 5410 automatic movement at 18,000 bph with hand-winding and quickset date, it includes toughened borosilicate crystal and 150m Parawater resistance.  The pencil style non - Mercedes hands for a distinctive look.

Collectibility and Value
These command $800–$1,500 USD on markets like Gem or auctions due to rarity and pioneering status among Japanese divers.  Servicing focuses on the integrated movement and crystal seals. 

Please see below photos:


40mm ase size, with straight pencils hands instead of the usual Mercedes hands.




Nice case back design with close attentions to details.
