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
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 :)
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 :)
