Only eight watches by Grant are known to survive with early lever escapements and two of these, the present lot and lot 43 are included in this auction.
The present watch, no. 2315, and its escapement are examined and illustrated in detail in Watches by Clutton and Daniels, an extract from their discussion is as follows:
“Grant exhibited in his escapement a lightness and delicacy
of construction that ensured its success from the beginning…
With such lightness of components the action is very vigorous
and enables the use of a longer lever; this lessens the unlocking
force at the roller and, for a given displacement of the lever,
reduces the lifting angle of the pallets, thus further minimizing
the friction…The action of the escapement is scintillating and
shows what can happen when a clever mechanic is left to play
with a good idea”. Clutton & Daniels, Watches, 1965, p. 114.
The dial’s layout is typical of those used by Grant, Emery, Pendleton and others for their watches with lever escapements. The early ‘YCC’ balance appears to be the first of four types accredited to Robert Pennington (see lot 54). Whilst Grant continued to use a straight line lever, by this date, his pallet arms embraced four, rather than five teeth of the escape wheel. With shorter arms, inertia was reduced and the lift was more efficient; moreover the shorter impulse faces had less friction, (see Camerer Cuss, The English Watch, p. 324).
