Part 2 Citizen Promaster Super Tough Titanium Robert Swan BJ8010-53E PMX56-2571 Year 2016...Superlativeness of this watch!

You've read the last article?...Some repeats here but who can help it?...

The Duratect Titanium Super Tough Robert Swan Citizen was released in 1999 as PMX56-2571 in the Promaster range of Japan only models. The rest of the world had the BJ8010-53E model number with slight cosmetic differences, uniquely in the depth rating designation "W.R. 20 bar" Japan-only and "W.R. 200" rest-of-world.


This is one rare pre-millennium superlative watch. Released in 1999 with a limited batch of five hundred units, I say again, rare superlative. I extrapolated my arguments somewhere that there could be more than 500 units simply because of the two differing model numbers but I could be wrong and then again possibly right, who knows? There are many good...super good...and exorbitantly expensive so watches out there. However almost all of them do not have a superlative title. This one has one and maybe two.

This is a Citizen Promaster Titanium Super Tough Eco-drive watch. The superlativeness of this watch, however, did not derive from the subjective 'super tough' attribute of its name but in its anti-magnetism aspect, an objectively measurable quantity. Rated to be resistant to 16,000 gauss (go Google some basic magnetism in Physics) and I'm just, like many of you out there, going to take it at face value of what Citizen had proudly done in their laboratories.


ANTIMAG 16000...Oh! missing the case back stuck on back plate! Good riddance.


16,000 gauss superlativeness...the often mentioned Rolex Milgauss is rated ten times weaker in this respect!

Now to put more fuel into the fire as to its name "Super tough". How tough is it? I have mentioned the Duratect titanium surface wear and tear toughness in my last posting prior to this one. The other tough attribute is its anti-shock features. It being any Eco-drive, ermm, quartz will have less need for anti-shock features...nevertheless, the lesser shock the better...


In anti-shock terms apparently quite well endowed as shown below....





From this illustrative diagram alone, one can see the excessive enough use of black shock absorbent seal material in protecting the inner watch cases while seated into the outermost watch case, all in titanium and Duratect treated.

Looking closely, the watch actually consists of three watch cases, with the innermost case securing the Eco-drive movement by seals all round its outer circumference, bottom seat and before an inner bezel ring securing down the dial. This forms the first layer of shock resistance.

The middle watch case(a monobloc) has a thick bottom seal that partially covers the outer stepped portion of the circumference of the case.  It is secured into the outermost case using four sealed screws. Picture above missing the seals in the securing screws! This forms the second layer of shock resistance.

Here the seals are shown. Middle case secured via four screws with seals.

Top bezel secure down crystal to the middle watch case through a thick black seal as well as pinning down an inner bezel ring that press against another inner bezel ring before the dial and the innermost watch case against the middle watch case, all with seals in between, of course.


This forms a floating middle and innermost case for the watch. The engineering, IMO, allows very slight movements to be absorbed and tolerated by the seals and clearances in the securing screws as well as the crown. A double shock absorbent design seems to be in place, phew!







As if that wasn't enough Citizen did another shocking treat for us customers....






This was adding another layer of anti-shock treatment...this time in isolating shocks from the all titanium bracelet! IMO, another unsung milestone achievement for this watch. How effective all these seals treatment towards shock absorbance are, I believe, lies in the clearances of the holes where the screw bolts through to give it leeway for the minutest movement short of metal impacts. I would call this feature the third layer of shock resistance.




Fully functional all titanium, surface hardened by Duratect, tri-fold clasp with divers extension built-in into the bracelet clasp. A rare find!

Angularly curved handsomeness...triple (as explained) shock resistance...anti-magnetic...tough Duratect Ti skin...500 rare...IMO, anti-gravity due to its weightlessness...love this watch!

Don't trade this for any other watch!...

So in conclusion, this watch is not only the most anti-magnetic watch in the world, it is also, IMO, the most shock resistant watch in the world, coming in with a triple shock absorbance design! A dual champion in the world of superlatives...that's pretty rare. I can think of another two superlative titles but enough for now. So the next time you are thinking of a trade-in for an Autozilla, think again. :-)
