Wrist Watch

MOST wrist watches are " gay deceivers 
Some are always in a hurry. Some 
are lazy ; and some are steady 
and sure, telling the time 
truthfully year in and year out Of th( 
last kind is the " Ltind & Water." 
The •• Land & Water " is one of tlio 
greatest achievements of the watch- 
maker's skill. It is the finest quality 
timekeeper obtainable and has been 
proved by practical tests in the 
trenches equal in accuracy to a 40- 
guinea chronometer. For Naval and 
Military men it is the ideal watch. It 
i? built to stand the jars and jolts 
inseparable from the conditions of 
modem warfare. The screwing-in of the 
movement into the specially built silver 
case, which is different to the ordinary 
way, renders the watch far more dust, damp 
and waterproof than any other pattern. The 
movement is fully jewelled and fitted with micrometer

A Thoroughly Reliable Compass 
at about half the price usually charged for 
one of similar quality and finish. The Com- 
pass is accurate, fully luminous, with a lumin- 
ous si^ht line on the ^lass so that it is 
e<)ually useful for day or night work. 
The card steadies with unusual rapidity, en- 
abling observation to be taken quickly, and 
the bulk of the in.strunient is no more than that 
of a flat dress watch. 
It is the best Compass obtainable for Service 
work at a reasonable price, and will fulfil all 
uses but those in whicli a prism sight is 
essential.

READ THIS FROM THE TRENCHES. 
Messrs. Birch and Gaydon ; Dear Sirs, 
I thought you might like to have 
some details about the wrist watch 
I purchased from you eighteen montlis 
ago. I have just arrived back in 
Ix)ndon on leave after fifteen montns 
in the trenches. The hands of tlie 
watch have never been sot since 1 
left England, and on checking the 
variation 1 find that the watch has 
gained less than two minutes in the fifteen 
months, Durin,' this time the watch has 
always been on my wrist, and has been 
tlirough many attacks in the Somme Battle, 
including the taking of • , etc., and 
on countless occasions has been subject to very 
severe dampmg.— A.H.H., loth Bn. Koyal Fusiliers. 
STEVEL WRISTLET (as illustrated), self adjustable. Fits all wrists 
— slender or stout. No straps, buckles, or other inconvenience. ' 
Enibles the watch to be slipped up the arm at wdsh-time, or turned face 
downwards, thus doing away with dial protectors. Strong and durable.

The " Q " Pocket Alarm Watch 
With luminou* dial. 
This Watch is a remarkably accurate time- 
keeper. The movement being of the best 
quality, fully jewelled, perfectly balanced and 
compensated for all temperatures. It is par- 
ticularly recommended for the use of officers 
in timing attacks, bombardments, etc. Equally 
suitable for civilians who, if they possess it, 
need never depend upon memory for punctu- 
ality in keeping appointments. The back of 
the case opens so that at night-time the watch 
may be stood at bedside ready to awaken you 
in the morning. The alarm is simple to set, 
and at the very moment of the appointed time 
a lengthy repeater-like sound will compel your 
attention. Should you fail to hear it (which 
is hardly'possible unless surrounded by noise), 
its vibrations are unmistakably insistent. 
Each Watch is fully guaranteed by the makers. 
(State wketlier black or wkite dial preferred).
