British Watches, Aircraft

Historical Background

The Royal Flying Corps was established in April 1912, incorporating the Air Battalion of the Royal Engineers, whose observation kites and balloons and fixed wing aircraft helped to form the basis of the Military Wing. The Naval Wing quickly evolved into the Royal Naval Air Service, which was established as a separate entity on 1 July 1914 under the control of the Admiralty. This separation of air power, which was never clear cut or even necessarily intuitive, continued throughout the war, with both organisations often competing for the same resources. Various attempts were made to cure the dysfunctional situation that had arisen, especially in relation to supply, culminating in the establishment, on 1 April 1918, of the Royal Air Force as an ‘independent’ force, ie as a third arm, separate from both the Army and the Navy. The RFC and RNAS were both disbanded.

Until 1918, the Admiralty developed its own requirements for an aviation watch and procured the Admiralty Type I and II watch. The Mark IVA watch was acquired by the War Office to meet a specification drawn up by the Royal Aircraft Factory. This was followed towards the end of the war by the 30-hour Mark V watch, which was probably procured under the umbrella of the short-lived Air Board.

Common Features of the WWI Aviation Watch

The archetype for British aviation watches was established from the start:

• nomenclature was applied to the dial (specifying, amongst other things, the contracted supplier of the watch)
• both luminous and non-luminous versions of the watch were issued
• markings were applied to the case to indicate military issue (except in the Admiralty Marks)
• an 8-day Swiss movement was used for the works (even in the Mark V, which allowed otherwise for 30-hour movements)

Nomenclature to the dial

The dials carried as a minimum the name of the supplier and the spec that it was intended to address (eg Mark IVA).

Individual serial numbers came to be applied later and most incorporated a letter code that identified the supplier. It was British standard practice during WWI to mark military equipment supplied under contract in this way.

The Mark V watches did not carry manufacturer’s names to the dial, but they are identified by their digraphic letter codes (and branding did appear to the movements, cuvette, inner case back, etc).

Luminous and non-luminous versions

Both luminous and non-luminous versions of the aviation watch were issued from the beginning (although use of the luminous version may have been confined to naval service).

Military issue markings

• Sterile case backs (no markings)

The Admiralty Mark I and Mark II had sterile case backs, apart from one version of the Mark II that was supplied by Thos. Armstrong & Bros, Manchester (which had a unique stamped ‘arrow’ design). Presumably the nomenclature that appeared on the Mark I and Mark II watch dials was considered sufficient for most purposes.

• A ↑ D dial mark (probably Air Department of the Admiralty) (1912-1915)

The A ↑ D mark is painted to the dial of Admiralty Mark I and Mark II watches and probably denotes the Air Department of the Admiralty. This Department existed only for a short time (1912-1915) before it was succeeded by the Air Section (and later the Air Division). ZMW [p 30] prefers ‘Admiralty Department’. The IWM Collection holds a stopwatch made by S. Smith & Son Ltd that is described as being marked ‘Property of AIR DEP ADMIRALTY’, but no photography is shown.

• A ↑ S mark (sui generis, possibly not an official ‘mark’)

An ‘A ↑ S’ mark appears to the case back of one watch only: the luminous Mark IVA watch supplied by S. Alexander & Son Ltd. The singular use of this mark, combined with the match between the initials used and the name of the supplier (‘Alexander & Son’), argues persuasively for the mark to be regarded as supplier's branding rather than a service designator. ZMW [p 12] attributes this mark to the Royal Naval Air Service c. 1914 (‘Air Service’), however.

• W ↑ D mark (War Department) (up to 1917)

The War Department (W.D.) mark (W ↑ D) was applied to the Mark IVA watch until that mark was cancelled in 1917. (See RAF Form 1048 ref: 2000/10/17, shown in KK [p 395]). At least two different designs were employed: an elaborate decorated version that occupied the whole of the flat portion of the case back; and a much smaller, simple, stamped version that is the more common usage seen in surviving examples.

Although the War Department became the War Office in 1857, the name remained in use for certain purposes.

• ‘Air’ mark (possibly Air Board) (1917 onwards)

The ‘Air’ Mark (A [underline] Broad Arrow] was applied to all Mark V watches (and to a very late version of the H. Williamson Ltd Mark IVA: see RAF Form 1048 ref: 2000/10/17, shown in KK [p 395], which specifies the small 9/32 x 3/16 inch version that was only seen on this watch). The use of this mark may reflect the reorganisation of war effort that led to the creation of the Air Board in 1917. However, ZMW [p 12] prefers ‘Aviation’.

• Air Ministry mark (inter-war)

The Air Ministry mark (A.M. with King’s Crown surmounted), which was used from the inter-war period until c 1944, occasionally appears in addition to one of the other marks, indicating retention in stores after WWI. These watches sometimes have ‘G.S. Type’ applied to the dial, indicating a General Service watch that in RAF usage was assigned the 6E/50 stores reference. (I have seen one Mark V watch with 6E/50 and the A.M. mark applied to the case back).

Eight-day movements

Before the 30-hour Mark V standard was formulated, the British aviation watch used 8-day movements from a variety of Swiss makers (not all of them identified). It is likely that 8-day movements were chosen for their inherent stability and accuracy rather than in anticipation of extended flying times. It was probably not until manufacturers could prove that 30 hour movements matched that requirement that the Mark V was specified and produced. (That is to say, the later adoption of the 30-hour watch reflects the evolution of Swiss watchmaking rather than a change in military requirements).

Octava Watch Company 8-day movement

The Octava Watch Co supplied movements seen in the Admiralty Marks I and II, the (putative) Mark III, the Mark IVA, and an anomalous version of the Mark V (which otherwise is a 30-hour watch). For a while, Favre-Jacot (better known today as Zenith) supplied a Mark IVA watch with a movement of this design that was marked with its own BILLODES trademark. (Later examples were marked Octava in the standard manner).

All Octava movements have serial numbers stamped to the base plate near the balance wheel, allowing broad sequencing to be established.

Unmarked Swiss gilt-finished 8-day movement

Serial numbers are stamped clearly to the main movement plate in a standard fashion, allowing broad sequencing to be discerned.

This movement is seen only in the Mark IVA watch.

(Eterna) Swiss gilt-finished 8-day movement

This movement was supplied uniquely by H Williamson for the Admiralty Mark II and Mark IVA watches. The movement is entirely different to the 7-jewel Astral movement that Williamson used for its General Service watches supplied to the British Army during WWI.

Serial numbers are stamped to the base plate of the movement, allowing broad sequencing to be established.

Douard Patent Swiss gilt-finished 8-day movement

This movement was used by Smiths to supply Admiralty Mark II watches.

The movements have serial numbers stamped to the dial face of the base plate, which is usually inaccessible.

British Watches, Pocket General Service

---

For most of WWI, the standard British military issue was a 7 jewel pocket watch, supplied by established firms like H Williamson, H White, and W Ehrhardt. All but the Ehrhardt were cased by Dennison (Ehrhardt being an established case maker in its own right).

Once the USA came on board, 7 jewel Elgin pocket watches were supplied also, c 1917.

Watches issued to the Royal Artillery need to be considered separately because they were entirely different (eg some hacked).

A Corporal of the Border Regiment wounded in the Somme battles of July 1916 mentions his issued pocket watch in an IWM interview: I can remember an RAMC man looking at me and saying: 'He won't live long...' and he took my watch out of my breast pocket - my official watch, suspended on a leather strap. Royal Army Medical Corps? Royal Army Robbing Corps more like!. To be fair to the maligned, removal of valuable officially issued items may have been a standing order in those circumstances.

British Watches, Wristlet

The starting point

Some trench watches bear the unmistakable signs of issue to the British Armed Forces: a broad arrow marking and/or an engraved alphanumeric sequence (an ‘issue number’). Genuine examples of these watches are rare, and reliable information about them scarce.

The starting point for most discussions of WWI British military-issued wristlets is ZMW [p 60]. This short but troublesome text states that:

• the British War Department obtained wristlets c 1917 for evaluation and issue (hence some collectors know these as 1917 evaluation watches);
• the watch dials used were black enamel with radium-filled numerals and hands;
• a number of different unsigned Swiss lever 15 jewel movements were employed;
• two designs of case were used: snapback and screw back;
• the snapback watches proved unsuitable in the field and were disposed of, whereas the screw back watches proved themselves and were retained.

Although I would challenge the first and last of these statements, a neat scheme is suggested whereby issued wristlets can be categorised according to whether their cases were of a snapback or screw back design, viz.

• the 38mm snap back;
• the various Dennison cased screw-back watches (3 distinct types).
