Fusee Chain Making

The art of making Fusee chains probably dates back to 1660 in London and is generally credited to Gruet of Geneva for their use in Clocks and watches. Tools for the manufacture of chains were very simple, consisting of Punches and dies, Hammers and anvils, a time consuming process requiring good hand eye coordination in candlelit conditions.

In the 1980’s, Jim Habgood, Chief Horological engineer for Smiths Clock and Watch resurrected the art of making chains based on the techniques of the workers from that bygone age. It was handed on to Mavis and David Hutchins in the late 1990’s who worked from their home in Devon keeping the skills and tradition alive. In December of 2013 they finally decided to retire passing on their well-honed skills to Sinclair Harding. After months of tapping and punching with quite a few false starts the process remains as time consuming and labour intensive as ever but the efforts have resulted in chains that maintain the highest quality standards set by Sinclair Harding.

We are able to make Fusee chains to order to any length required, the size of our No 4 chain (1.3mm w x 2.8mm h). If you would like a quote for a new Fusee chain or a repair then please contact us.

The chain making process

Start of the chain - Each inner and outer link is hand pressed. The inner links are hardened and tempered.
Each pin is loaded into the inner link. 
The pins are then pressed into the inner link forming a sub.
Each Sub is placed into a block where an outer link is placed inbetween each sub. This is repeated until the chain is built up.
The chain is gentle pressed to crimp the chain sub.
Each pin is individually riveted.
The chain sub is now filed.
The chain is built up set by set, 16 sets of chain are made to complete our standard chain. A total of 510 pins, 765 inner and outer links. 
The finished chain is worked to check for any loose rivets, then it is inspeced, cleaned and oiled.
Our very first chain!
Each chain is tested to 28kgs with a safe working load of 11kgs.
