Seiko 5ACTUS SS from 1972 in excellent condition, all original except the bracelet which is new, quality, stainless steel, Duralex brand.

I'm not sure but I think the "SS" sub brand was a Japanese domestic release only. And also not sure that the "SS" stands for "Second Setting". All the SS models I've seen house the 6106 movement which features hacking (stopping the watch when setting the time) allowing for synchronized setting. 

The condition is, overall, exceptional. The iridescent, pale cyan dial is excellent except for some aging of the "5ACTUS" printying. The hands are mint. I found the iridescence hard to photograph. 

The case has been lightly re-finished and presents beautifully.

The crystal is new, replaced in the overhaul.

The 6106 movement is a variation on the 6119 which is, in my opinion, Seiko's best ever movement. It features hacking. It is in pristine condition. It has just been professionally overhauled/serviced and functions perfectly.

Caliber number 6106C
Case number 6106-7520
Serial number 2N1672
Dial reference 6106-7690T

Overhaul/Service explained

I am often asked about what an overhaul entails. So I have started adding a photo of the movement, disassembled ready to go through the cleaning machine. All old dried up lubricants, crud and anything else that shouldn't be there is cleaned away. Then, it is reassembled, lubricated, adjustments made and regulated.

SEIKO 5 HISTORY (provided by a colleague trading on Ebay as market*master):

First released in late 1963 the Original Seiko 5  is a modified SEIKO SPORTSMATIC.

Seiko decided they needed an affordable watch that was versatile and durable. An everyday device that could handle a wide variety of different situations and environments. So was born the '5' concept.

The '5' came from the 5 features they wanted to incorporate into the watch.

These were:

1. Automatic winding

2. Day/date display

3. Water resistance

4. Recessed crown at the 4 o’clock position

5. Integrated metal bracelet

The '5' was an immediate success and has gone on to become the most successful line of mechanical watches in history.


About vintage mechanical watches:

A vintage mechanical watch will not perform like a modern quartz (electronic) watch. It is not ideal as a daily wearer. It should be treated for what it is, something old, classical and special.  Treat it as you would a vintage car - not ideal to use as a “daily driver”. Keep it in the condition at which you bought it and it will hold or, indeed, increase its value. Use it every day and it will go backwards.

 About Me:

I am a born again watchmaker! I finished my apprenticeship in 1973 having completed technical training at the RMIT, Melbourne. In the early 80s I went into retail (jewellery and watches). About 25 years ago I realised that the watches that once were common had become rare and I began to appreciate their beauty both in style and mechanically. That’s when I started collecting classics. When covid hit, I retired from retail, set up a workshop at home, regained my skills and am now restoring classics with a passion.
