Avia Daytyme 30 Jewel Automatic - Felsa 4009

7/6/2016

Automatic mechanical wristwatches have been around quite a while and no matter how many i see they all seem to blend into one another, but every now and again you come across something a little more special. When you think of a mechanical watch with a day & date compication you'd usually think of a Seiko or maybe even a ETA based watch but we often forget how stunning the vintage day/date watches were and this Avia Daytyme is truly a blast from the past :)

Movement - Felsa 4009 - 30 Jewel Automatic

Specifications

11.5"' ( 26mm ) - 17/21/25 Jewel Standard Movements - 18,000A/h - Sweeping Seconds
Production - 1960-1970's 

Similar movements by Felsa / Calibres 4019/4008/4018

The particular movement of this Avia has an additional 5 jewels added to take the total to 30 Jewels, the additional jewels are added in form of screw down cap jewels for the drive train pivots both upper & lower. 

Condition - Arrived barely working but with day & date functional, overall good condition but dried up lubrication and debris was clearly hindering the movements function, a good service should see the watch right again. Time to strip down and prep for cleaning >
​
As can be seen form some of the strip down process the movement is in good condition with only debris and dry lube stains that stand in the way. Sadly my camera battery died before i could take anymore photos of the strip down.

Watch Assembled For Testing

With the movement serviced the watch purred into action and timekeeping was surprisingly good for the age. As can be seen below, the timegrapher is showing pretty healthy results considering the movement has't been  regulated yet :)

Completed Watch

With the movement serviced, casing polished, new armoured glass, new crown, the watch was ready to be fully assembled with a new strap and made ready to wear. As you can see the watch is truly back on form and ready for a new owner :)
Truly a gem of a watch and one to  be proud of in any collection ! Gold watches are unfortunately not suited to me ( or at least ive yet to find one ) so this one will be up for grabs in my ebay shop at some point.
 For now its back to bench for another challenge :)

Coming next time....

Next up..... Seiko 7625 Automatic - Classic Seiko Design

Dear ...Author,

I have got this watch yesterday from London via ebay.com.
May I ask You, how to change/move the date and calendar? I tried with crown, but they moves only arrows, equal in which position.....
Thank You.
best wishes for 2017

Hi Dmitry

The day is changed by forwarding time 24 hours, the date can be adjusted by forwarding 24 hours then reverse to 21:15 hours and back to 24th hour.

So simply put, forward time until day changes over then reverse the hands to 21:15hrs and back to 24hr ( 12 O Clock ) and repeat until desired date appears. This should all be done in the time setting position of the stem.

Hope it helps

Regards
