| | ====== Seiko 6100 ====== |
| | The "Seikomatic 5" **6100** series was a family of mechanical watch movements from [[Seiko]] in the 1960's and 1970's. |
| | |
| | Produced from [[1967]] through [[1974]], the 6100 family was used in many high-end Seiko watches. It was available in both regular 21,600 A/h and [[high-beat]] 36,000 versions and both [[manual winding]] and [[automatic]] versions. |
| | |
| | The [[Grand Seiko 61GS|Hi-Beat 61GS]] models, introduced in 1968, upstaged the slower [[Grand Seiko 62GS|62GS]] models. That movement was retired in 1969, with the 6100 becoming the high-end Grand Seiko movement. But producing these movements was highly labor-intensive, so Seiko began mechanizing the next year. The [[Seiko 5600|5600 calibre family]] quickly proved itself for reliability and quartz movements boasted better accuracy, leading to the demise of the 6100 by [[1974]]. |
| | |
| | Seiko "resurrected" the 6159A movement in 1975, creating the 6159B for their 600M diver. There is little parts interchange between this later movement and earlier members of the family. It features larger pins to attach the heavier hands of the diver, along with different balance cock and regulating pins similar to the [[Seiko 4S24]]. |
