My first ‘proper’ watch was the Speedmaster cal 1045 and ever since I have been a big fan of the central minute hand configuration for chronographs.
The Omega cal 1045 movement in this watch is derived from probably the most well known movement of this type, the Lemania 5100:
I have also been lucky enough to own the lump that is the Omega Speedmaster 125, that carries the Omega cal 1041, (derived from the Lemania 1341) and the movement that claims to be the first automatic winding chronometer rated chronograph.
Obviously the primary supplier of this, (mechanical) style chrono movement is Lemania but the movement itself, (or derivatives thereof) has been used in a huge range of different manufacturers watches, including:
Lemania themselves, Omega, Sinn, Tutima, Orfina, Heuer, (great guide here: http://www.onthedash.com/Guide/_Chronog ... 00_Series/ ) Wakmann, Tissot, B&R, Fortis and this list is far from exhaustive…
(One I missed is Diavoli Rossi - viewtopic.php?f=3&t=227355 - surely the cheapest 5100 powered watch I have seen for a while!)
My latest watch , (in case anyone missed it) also houses a 5100, the EZM1:
Then there is also the quartz version used in Eddies PRS17 and a Revue Thomnen amongst others.
Most lately there has been the Sinn EZM10 housing the SZ01 movement that Sinn developed from a base Valjoux 7750 to have the central minute counter and recording a full 60 minutes elapsed time.
Next year rumour has it that Sinn will be releasing the new 140 range with the SZ01 movement – more here: http://tz-uk.com/forum/viewtopic.php?f=1&p=2211300 – some say, like the EZM10 it is overpriced and I tend to agree, although with the years of investment to create the SZ01 I suppose it’s understandable…
Please share your thoughts on the central minute hand chrono layout – and more importantly post up your pics, the more the merrier, but it would be great to see some of the rarer watches with this configuration as well as the usual suspects!
Cheers,
Rob
