How many daily winds on my Timex M-105 Marlin?

[fclass308]

I finally finished my 1980 Marlin 81-D and decided to wear it for a few days to see how it performs. My Black Bay Pro is sulking in the watch box. 

I regulated it on my Time Grapher down to +5 SPD-ish after servicing and lubricating. Pretty surprising to me. I hope it will run there or there-abouts but it's going to take a few days wearing it to see.

I have never had a manual wind watch. I have a few automatics so I never had to consider winding the watch regularly. I am wondering if there is a preferred number of winds to wind it in the morning?  I would like give a stable a power availability but not wound fully so as to preserve the mainspring if I can.

Fully wound up would give you better amplitude and timekeeping compared to partially wound.  If i were thinking like you though i would count the turns of the crown through my fingers to achieve fully wound from fully unwound, time the power reserve from full wind and  knock off maybe 6 hours and calculate how many turns you needed for that amount of reserve.  After a few days of trial and error you will conclude the optimum reserve that will give you reliable time, which again for the most reliable is practically fully wound same as your automatics would be at the end of your day.

 Wind every 12 hrs and up to 90% of full wind each time. That helps keeping power supply a bit more steady,  compared to winding every 24 hrs.

To improve on steadiness of power supply, one can wind three times a day, thats winding every 8 hrs.

Where in Sam's hill ,did a single wind per 24hrs come from. It rather has to do with our mindset,  habbit, but  has no technical significance.

You seek steady rate, keeping power supply steady helps.

Makes sense but us humans are not sensible, just think we are.

I agree with @Neverenoughwatches that a watch should spend most of it's life in the fully/almost-fully wound condition, in this 'zone'  the watch will be working at peak efficiency = accuracy. This is the real reason automatics are more accurate than manual wind, as they keep the spring constantly topped up and working in that highly wound and therefore accurate zone, not because we are too lazy or forgetful to wind them up.

I tend to give my manual watch a full wind in the morning and then top up during the day, while I am in the lift, waiting in line for my coffee, pretending to listen to the wifes day at work etc...

@Nucejoe Just a quick question, how do you know where 90% is so you can stop at 90%?

Following reassembly everybody is anxious to test the watch, guess that be a good chance to wind from zero to full wind , and figure out number of turns to 90% , just to have a figure for long use.

When on wrest,  keeping power supply steady ! helps steady rate. 

A single 100% wind, wont stay 100% all day, thus no steady power, to expect steadiness with other factors.

 fully wind each day..

BTW what is 81-D?

There is one on ebay that uses that designation. I'm guessing that's wrong...

yep, no such thing as 81-D   movement or model.  it might be an ink stamp instead the case back .
