Just picked up this terrific slightly used 7015-7000 Speed Timer on the original bracelet. I am stoked at how nice it is. Once I give it the full disassembly, ultrasonic cleaning, etc with new NOS crown treatment, this one will be special!
2 Technical Questions for our SCWF Experts:
1. Being based on the 7005/7006/7009 caliber, with the start-stop chrono mechanism added on top, is it better to leave the seconds timer running (like a 6138 or 6139 movement) or better to leave it stopped unless timing ?
2. Does anyone know for sure if 6139 model springs can be used for the start-stop buttons in the 7015? I have a spare NOS set of 6139 springs that I would like to use when I reassemble after cleaning.
Thank you in advance !
