Automatic, TPD and Direction

[ianblyth]

One of the things that I was surprised about when I bought my first CWL watch was that there was no information about the turns per day (TPD) or even which direction for any of the CWL watches. I know some people have made comments about watch winders but I find them useful. Even the CWL manual says

Try and wear your watch everyday, if possible, as this will both enable it to keep better time as well as preventing the lubricants in the movement from solidifying.

After a bit of searching and a couple of useful posts in the forum I have the information. Mainly from http://www.orbita.net/pages/17100.htm.

I have made a list of all the current CWL models and how many TPD they need and direction.

Model Name Turns Per Day Movement
C5 Malvern 650 - 800 Both ETA 2824-2 / Sellita SW200-1 (25/26 Jewel customised)
C5 Malvern Aviator 650 - 800 Both ETA 2824-2 / Sellita SW200-1 (25/26 Jewel customised)
C8 Pilot 650 Both ETA 2824-2 (25 Jewel)
C15 Henley 650 - 800 Both ETA 2824-2 / Sellita SW200-1 (25/26 Jewel customised)
C20 Lido Forum LE 2009 650 Both ETA 2836-2 (25 Jewel)
C40 SpeedHawk Chrono 800 CW ETA 7750 Valjoux (25 Jewel)
C80 Sector 650 Both ETA 2824-2 (25 Jewel)
C600 Tri-Tech Diver Elite 650 - 800 Both Sellita SW200-1 (26 Jewel)

CW = Clockwise
CWW = Counter Clockwise
Both = either direction

I have seen contradictory numbers on other web sites (usually higher) but this is a good start. Hope someone finds it useful.

PS - it is hard to paste a table in here.

Great Job Ian. Thank you.

I have found the Orbita site most useful in the past.

You are correct about trying to post a table. It just doesn't work well.
