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.

      Is this a 'hack' ?

      By nevenbekriev · Posted

      OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.

      Any tips to correct a sloppy error?

      Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.

      Setting lever spring

      By mikepilk · Posted

      The stress is the force (on the spring) x distance. The maximum stress is at the bottom, and decreases up the arm. That's why they always break at the bottom. I used a round file, then something like 2000 grit to finish. I gave the rest of the arm a quick polish - no need for a perfect finish. Just make sure there are no 'notches' left from cutting/filing. The notches act like the perforations in your toilet paper 🤣

      It's probably a cardinal rule for watch repair to never get distracted while at the bench. Yesterday, after finishing a tricky mainspring winding/barrel insertion (I didn't have a winder and arbor that fit very well) I mentally shifted down a gear once that hurdle was passed. There were other things going on in the room as I put the barrel and cover into the barrel closer and pressed to get that satisfying snap. But when I took it out I realized I never placed the arbor.  When opening a barrel, we are relying on the arbor to transfer a concentrically-distributed force right where it is needed at the internal center of the lid. However, when that isn't present it's difficult to apply pressure or get leverage considering the recessed position of the lid, the small holes in the barrel and the presence of the mainspring coils. It was a beat-up practice movement so I didn't take a lot of time to think it over and I pushed it out using a short right-angle dental probe placed in from the bottom, but that did leave a bit of a scratch and crease in the thin lid. I had also thought about pulling it using a course-threaded screw with a minor thread diameter smaller than the lid hole and a major diameter larger, but that may have done some damage as well.  Thinking about how this might have been handled had it been a more valuable movement, is there a method using watchmaking or other tools that should extract the lid with the least damage?

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      🤔 what happens if lubrication is placed directly on top of epilame ? Making a small groove so the lubrication doesn't spread across the component but what if when lubing a little overspills and sits on the epilame .
