Early Howard watches featured innovative safety barrel and regulator designs, and many had quite elegant finish.
The firm experimented famously with early appearances of Breguet overcoil and helical hairspring configurations and escapement variations, including several, such as Cole's resilient banking escapement [4], with innovative banking methods. At the same time, the company's jewelling and predominant springing practices were archly conservative, as was their heavy reliance on traditional craft methods.
Between approximately and or , Howard's dial room foreman, Josiah Moorhouse, painted and often signed a number of exquisite dials appearing on some Howard watches of the period. Most of these dials, whether with or without a written signature, bear Moorhouse's equally unique artistic signature described in [6].
The Howard firm rarely applied model designations to its watch movements, leaving it to collectors and horologists to develop their own naming conventions for Howard watch movements after the fact.
The oldest, most familiar, and widely used naming convention for Howard watch movements is the "Series" scheme invented by Percy Livingston Small [3] and later popularized by Hacket [7], Townsend [8] and others. Small's scheme divides Howard watch production into twelve series based on contiguous serial number blocks.
The scheme strives, but does not always succeed in keeping movements with different combinations of size i. More recently, Geller [4] has developed a naming convention employing both information from surviving Howard watch movements and that from the factory records, the majority of which became available for study in The new scheme eliminates various ambiguities and issues with the series scheme and supplies introduction dates as part of the naming convention, making it a potentially better tool for research and for communication among collectors.
However, since the newer scheme is less familiar to most collectors at this time, corresponding model names from both schemes are cross-referenced in several places in this article in order to minimize confusion. A complete list of model name correspondences between the two schemes also is provided in Table 1. The Howard company's standard watch products are summarized in Table 1, in which movement types are referenced both to the series designation scheme of [3] and the newer scheme introduced in [4].
Examples of all standard types from the Model all varieties through the Model a. Their unique movement sizes, together with both the fact that the Howard firm never manufactured its own cases and the low survival rate of gold cases generally, have combined to make the identification of correctly cased Howard watches important to collectors [9]. Note that Reed's patent really describes a main wheel rather than a barrel, but it is customary to speak of Reed's invention as a form of patented barrel.
The Howard Model design famously employed separate mainspring barrel and train plates, most often but not always graced by lenticular cut-outs. Split plate models were manufactured in L and N Size, and in both open face and hunting configurations. Gold flashed damaskeened finish [4], and nickel damaskeened finish both were introduced on the Model N.
Pendant or stem winding and setting debuted in the Model Howard's new steel safety barrel, which was actually a barrel, also was introduced on the Models L Size and N Size. In , Howard introduced a new G Size ladies model his first ladies model being the Model I Size keywind, of which only were made.
All his G Size watches, except for those in the first hundred lot not all of which were made , were stem wound and lever set. The transition from key to stem winding was completed in Models through a.
Series V, IV, and VI , and solid nickel plates which were always damaskeened were introduced in these models. In the 's the Howard firm introduced Breguet overcoil hairsprings into its regular production line, as well as center hole jewels, which raised the total movement jewel count from 15 to This was the same period in which the Howard firm's only known private label movements were manufactured [11], open face and 22 hunting case movements for Webb C.
Ball of Cleveland, Ohio. The marking, "Adjusted," on a Howard movement usually signifies a watch that had been fully adjusted to HCI6P at the factory. See below. Table 1. A few very late examples signed "E. Waltham Model [2] material finished in Roxbury with Howard modifications, circa ; 16'th jewel on pillar plate side of center wheel. Type D with cut-back barrel plate; 1'st single banking pin SBP escapements [4] appear among this model.
Perhaps a few more than K size movements were produced. Last model with Mershon's reg. Adjustment markings became standard and dust rings were introduced during this model's production; Transitions occurred in this model from: balance over, to under center; blunt, to toe-ended, to club-footed escape wheel teeth; stepped to straight balance cocks; case screws on pillar plate to c.
Between and I Size movements were produced. First Howard watch model for ladies. Unique plate and escapement variations are known. One 21 jewel example of this model is known.
This model is actually 16 Size, rather than L, and has an integral, vestigial dust ring i. No formal grade designations for Howard watches were in use by the company prior to For a discussion of Howard quality levels in production prior to this date, based on factory record data and surviving movement data, see [4, and especially Table IIa on page 86].
A system of seven numerical grades, described in Table 2 below, was introduced in and expanded to cover all subsequent production in July of [4]. The system was based on the type of plate finish gilded brass, or gilt or nickel damaskeened ; the type of regulator simple, or "patent" [i.
Prior to other factors affected movement price as well, such as the type of balance wheel SSB, SGB, or compensated , and the method of winding and setting key versus stem.
