Affordable Vintage: Seiko 6138-0030 "Kakume"
Of all the incredible chronographs produced by Seiko in the 1970's, in my opinion there is one that stands head and shoulders above the rest: The 6138-0030 aka "Kakume". During this era there were two main chronograph calibers used, the single register 6139 and the dual register 6138. The fiercely popular 6139-600X (aka "Pogue") chronographs get the lions share of attention due to their status as arguably the first automatic chronograph in space, having been worn by William Pogue during space flight. By comparison the 6138 series is under appreciated, but it definitely stands tall in its own right.The 21 jewel 6138A released in 1970 was the first fully integrated automatic chronograph with a column wheel and vertical clutch coupling mechanism. Some time later, they switched to the 23 jewel 6138B. They are both automatic (rotor winds in both directions like most Seiko calibers) and hand windable, which is uncommon in vintage Seikos, and the day and date feature a true quickset mechanism

5146 caseback height
Hi,I am far away from a PP dealer, so not able to see models 'live' as easy as some of you. Could I get owners of the 5146 to take some side shots, and comment on how high the watch sits on the wrist - perhaps compared to other pp models or other brands? ThanksSent from my iPad using Tapatalk HD

Is it worth to trade my 5712r for a 59801A?
i have been thinking of getting the 5980ss for a while now, don't really know how hard it will be to obtain one since it's being discontinued, so i guess my best bet is the second hand market. I 've got my 5712r almost 2 yrs now, don't know if i should trade it for the bigger size nautilus?
