I just picked up a Parnis from this seller: eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

Arrived promptly and well packaged.

At 9 o'clock there is a dial with 14 increments 0.5, 1, 1.5, 2 and so on. I presume these is intended to tick over 1 increment at midday and midnight of each day of the week, to indicate the day of the week and to indicate am/pm? If my assumption is correct, it appears not to be working correctly. When I wind the watch forwards manually, it moves forward 2 increments per day - first increment at 1am and second increment at 3am.

Would anyone mind confirming if my assumption of what the dial is meant to indicate is correct, if you think it's not working properly and, if it's not, if it's something I can adjust/correct?

That aside, as someone who knows nothing about watches, I'm happy with what my untrained eye perceives to be pretty good build quality. The one caveat is that the back of the clasp (the bit that actually contacts the skin on the inside of your wrist) has very squared-off edges rather than smoothed-off, rounded edges so it can become a bit uncomfortable after a few hours wear.

Here's a pic for anyone who may be interested.

I'm also considering having a go at regulating the watch. Will get myself a basic toolkit off eBay and see what I can do. Here's a couple more pics - the first shows the squared edge on the clasp that makes it a little uncomfortable after a few hours of wear and the second shows the mechanism. I can see where the + and - is to perform the regulation but as someone new to this, it's unclear to me which bit I want to be adjusting in the directions of the + and -. Do I put a tool into the gold-coloured middle of the adjustable part and tweak it left and right or do I adjust it by tweaking one of the 2 silver coloured levers that protrude from the rear and side of the adjustable part? Thanks in advance.

Hi Welcome to WUS To adjust the rate you need to move the small silver leaver with the gold dot on it by tiny amounts in the plus or minus direction until you get the watch as accurate as possible. How is the watch performing at the moment is it running very fast or slow ? I Have a watch with the same dial lay out and the day of the week indicator functions as you described moving in two increments at night so I assume yours if working as it should. I know what you mean about the buckle I have the same one on a couple of watches I spent some time sanding them down to make them more comfy.

Thanks balla.

I understand there won't an accurate answer to this question but, in order that I have a rough idea what I'm aiming for, what kind of gain/loss would one ordinarily expect to achieve by using the fullest extents of the calibration in either direction? I haven't measured it accurately yet but I reckon it's gaining about 15 seconds per day. Problem is, I've no idea if that's equivalent to a big shift of the adjustable component or just a faint tickle.

hello, its a trial and error if you dont have any watch timing device. in order to get the correct beat, you should do the six position method. i have been regulating my watch for almost a week just to get it to run -5+ /day

Thanks nuj - I understand that it's a process of trial and error, tweaking until you are satisfied with the result, but my question isn't about the method that one would employ to regulate the watch, per se. Rather, it is wanting to understand roughly how much a typical mechanism would allow me to adjust in either direction. By that, I mean would the approximate difference between an adjustment regulated fully in the + direction and an adjustment regulated fully in the - direction be, perhaps, 5 seconds? 30 seconds? 120 seconds? I'm sure that with a bit of fiddling I'll start to gain a feel for what the limits are but it would be helpful for me if someone with a bit of experience of this gave me an indication of what the limits are.

Thanks.

Thanks Citizen V - just what I needed. Unfortunately, I had my first attempt at tweaking my watch before noticing someone had replied and I overcooked my attempt to slow the watch down but I do now have a bit of a 'feel' for how much I need to be moving the lever to achieve the kinds of adjustments I'm hoping for.

With a bit of fiddling over the course of a week or so, using a wooden cocktail stick, I've now got it running about 1 second per day slow. Presume that's a decent enough result without any specialist kit?

Only issue I'm now suspicious of is that the dial which I'm presuming indicates the month didn't tick over automatically a few days ago. It ticked over fine using the button on the side of the watch, however. Would be a shame if there's a fault with it now that I've finished messing about regulating it.
