Sekio watches and my Bell-matics

My collection of Seiko watches that i collect or have collected and the ones i still desire !!

My main area of interest is the Seiko Bell matic, this blog shows the ones that i have collected, or "restored" for myself and others and watches i have for sale or trade.

I am always on the look out for Bell-matic parts/spares every thing from bracelet parts to complete watches to complete restorations now and in the future, if you have any thing for sale or trade please contact me.

Dating a Bell-matic.

Dating a Bell-matic is straight forward and done using the serial number stamped on the back plate, Bell-matics were produced from as early as 1966 through to 1977.
  • Waterproof stamped on the back #956789, the first digit "9" is the year which in this case is 1969 because the "proof" mark was only used until June 1970 (approx), the second digit "5" is the month, so May, the last four digits are the number of watches produced in that month.
  • Water resistant stamped on the back #7D6789, so "7" is 1977 because we know water resistant dident show until after June 1970, "D" is the month, in this case December and the four digits again is the number produced in that month.
  • Year digit 1 to 9 is January to September the O is October, N is November and D is December.
