Omega Seamaster Calibre Production Tables

In January of 2004 a new Omega Seamaster book started appearing on eBay. With the help Tywebb on the TimeZone Omega Forum, the ISBN number was determined and the book was found on Amazon.co.jp... This book which Bablefish and others translate as "The Omega seaming machine star story" is available via Amazon.co.jp and even with express shipping the cost is a reasonable at around $35. Inside the front cover is a slew of Calibre tables which are replicated below. I am presenting these tables under Fair Use provisions in the copyright code. I encourage all who are interested in Seamasters or use these tables to pick up a copy of the book. Even though it is in Japanese the pictures alone are worth it! If you have questions or corrections please contact the author...
