And then there were three

So now I can probably call it my little collection.

I deeply regret, though, that I sold my Rolex Submariner that I wore daily for 14 years. In 1982 it was an affordable watch.

I had several watches over a number of years, after the Rolex, that I either sold or gave away, shouldn't have done that.

Started to think about keeping them when i got my gold watch after thirty seasons at the ski school.

When it comes to accuracy, please Note:

1.Solar powered to a rechargeable battery.

2.Kinetic powered to a rechargeable battery.

3.Quarts powered from a "normal" battery,

are measured by the month or even over a year.

Citizen, as i am familar with, recommend to change the rechargeable battery every 10 years or so.

Mechanical watches, on the other hand, are measured by the day. As I recall, the official accuracy for a chronometer should be within -4 / +6 sec. a day. But, be aware of the fact that it is so many factors involved when it comes to accuracy in a purely mechanical watch. Things like: How you move, temprature (which is very important)  and where you are, geographically speaking, across the globe.

And try to keep a mechanical watch away from strong magnetic fields (like high end speakers as an example).

Highly recommended: Open all the various links in new tabs!

Citizen "EcoZilla" 

300 m. Professional Diver

Solar Powered

Aprox. accuracy

+5 to +10 sec. monthly

I've had this one for 9,5 years, just about now.

Read this consumer review with some good photos:

Certina Gold Collection

My 30 years anniversary Ski School watch.

I am very proud to wear this in more formal surroundings.

Quarts Powered

Aprox. accuracy

+2 sec. monthly

Seiko Prospex Automatic Divers SRP 779

Also "nicknamed" The Turtle.

Automatic movement 4R36

which is Seiko's In House movement.

Power reserve is aprox. 40 hours

Accuracy: After 8 days on my wrist it is off by -17 sec.  which is very good, indeed.

Now, after the 14 days of "run-in" time it was -42 sec. off which is an average of 3 sec. a day. That is amazingly good for an entry-level diver's watch, actually within the international standard for Chronometers.

I will keep you updated over the next months


I corrected the watch today, i will make that a habit every time it reaches 1 minute off.

In the first 25 days it was -65 sec. off which is an average off -2,6 sec. a day.

I am very happy.


So, now the watch have been travelling and there is changes to it's behavior.

Twice on a plane, been swimming in the Black Sea and 14 days in temperatures around +30 degrees Celsius.

In those 16 days the average has been -7,3 sec. a day. So now it will be interesting to see how it will behave when back in it's "normal" enviroment.


August 6th - September 12th 2016

I guess it has somewhat stabilized itself on a level that is more normal for an entry level diver's watch.

In this period it's daily average has been -5,5 sec. a day.

Am I still happy?

Ohyes, I am.. so until next time, enjoy yourselves.


September 12th - October 20th 2016

In this period of 39 days it has lost 174 sec. which is -4,4 sec. a day. So it varies some. Anyhow, it is as I have stated earlier, very very good.

So again, until next time..


Octtober 20th - December 7th

49 days -300 sec. which is -6,1 sec. a day

Holding up very good -:)

I will, when I get hold of a proper camera, get a couple of luminous photos of the EcoZilla and the Turtle.

They are both quite bright and lasts for hours.

When it comes to actual water resistance you shold probably read this article and articles like it:

I was, originally, about to buy the Seiko SKX 009 but after I saw this video.. well, I went for the new Turtle:


A review of the new Seiko Prospex SRP 777 'Turtle', one of Seiko' new releases for 2016. This watch is a re-issue of the classic Seiko Diver reference 6309-7040.   


The SRP 7** series comes in four models.
