Back in the summer I acquired a military style Seiko 5 watch.

Fortunately I was able to aquire the latest version.

This is a beauty and fitted with the comparatively new 4R36 movement which supercedes the old 7S36 though the movement is still abundant.

The 4R36 has the hand wind facility and hacking. This watch is accurate and with me gaining 3 seconds a day. See the pics and the timegrapher at dial up.275d04e9ecda178a4b599851e15532ef.jpg1dc6010ebd4453fbe66431025055cb71.jpg11370b50aadd895cdb7e3ac030144817.jpg

Nice acquisition.

I have had quite a few watches with new 7s26 and more recently some with 4r36. My experience is that the 4r36 seem to be more accurate out of the box but they're basically the same as the 7s26 apart from maybe an extra 3 jewels. I don't know if it's because they're being regulated better at the factory or whether the extra jewels have an influence.

Current 4R36 include a SRPA21, SRP777 and a modified SRP275

To be exact, the 4R36 is not a "latest version" and does not replace the 7S26, which remains in production, mainly for marketing reason, as it allows Seiko to segment their mechanical watches offer, that is Seiko 5 "non Sports".

Possibly I should of been more precise. It's the latest version of a military style watch for me.
The photos clearly show its a sports model I thought ?

SRP515? What's in a model number anyway?! NICE watch...love my 4R, although if I'm late or early for some event,

I usually don't blame my watch, (it's easier to blame the wife, kids or the dogs!):thumbsu:

Yep it's the Model SRP515. Which is a sports model and not the basic "5" Which I may inadvertently lead people to believe. The later sports models seem to be fitted with the 4r as opposed to the 7s.
Whether this is a trend or not I couldn't say, not being privy to Seiko marketing secrets. Anyway regardless of model, it's a great watch.
My other Seiko "Military Style " is the basic and fitted with 7s26-c movement with its revamped "Regulator " with longer pins as opposed to the 7s26-b which the general accusation seems to be that the hairspring can jump the pins with a mild impact.
This is a great watch as well.

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.

      Unusual Seiko dial damage

      By tIB · Posted

      Potentially not the right place to post this and it's one of those where I'm not looking for a solution but rather thought you'd like to see it... Picked up a sketchy looking 6105-8000 the other day, the dial on which I've never seen the likes of before... The paint has literally solidified and lifted away from the dial in places, I'm some parts completely (and has been touched up with a matte black).  I showed it to someone who works on and has a healthy obsession with these things - they told me they've seen this before on less than a handful of old Seiko dials, and think it's caused by water sitting on the sides and corrosion.  It's quite a mess, but at least most of it is still there! Not sure about that relume either, though I should add I went to this eyes wide open price wise and the rest of the watch is good.  Pics:
