Genesis and Evolution of the Annum

The journey of the Haim Watch Company Annum began with a vision to democratize the complete calendar complication, a feature historically reserved for more exclusive and expensive watches. M. Zakir Miah, the driving force behind the brand, has consistently demonstrated a talent for reinterpreting classic complications through accessible designs. The Annum’s development can be traced back to his initial interest in the intricate mechanics of perpetual calendar movements, specifically drawing inspiration from ETA’s long-discontinued 2890-9 perpetual calendar module. Miah’s original ambition was to develop a true perpetual calendar watch. However, the scarcity of available NOS (new-old-stock) movements, many of which were found to be in poor condition, presented a significant hurdle. This challenge, rather than deterring him, spurred a more direct approach: designing and engineering a proprietary calendar module to integrate with a reliable base movement. This "do-it-yourself" ethos, a hallmark of successful microbrands, has resulted in the Annum as it stands today – a testament to ingenuity and a commitment to horological innovation. The prototype seen at the WindUp Watch Fair was a crucial step in this evolution, allowing for direct feedback and refinement before the final production model was released. The subsequent design adjustments, including the case and dial tweaks, reflect a meticulous attention to detail aimed at optimizing both aesthetics and functionality.

Dial Variations and Aesthetic Appeal

The Haim Watch Company Annum is available in three distinct dial configurations, each offering a unique visual experience: "Dark Cobalt," "Stone White," and the particularly captivating "Fumé" option. The "Dark Cobalt" and "Stone White" variants present a classic aesthetic, featuring solid-colored dials characterized by a sunken CNC-guilloché center section. This intricate texture is framed by a grained outer dial ring, upon which applied hour markers are precisely positioned. These dials exude a sense of traditional watchmaking elegance.

However, it is the semi-transparent "Fumé" dial that truly distinguishes the Annum, offering a modern and intriguing interpretation of a complex dial layout. From a distance, the "Fumé" dial evokes the allure of vintage skeletonized perpetual calendars, its smoked semi-transparent PVC (plastic) material revealing the intricate mechanical module beneath. This transparency is artfully balanced with printed white and blue subdials and minute track, and a white outline around the moonphase aperture at the six o’clock position. While this design choice sacrifices some of the tangible depth found in solid dials, it compensates by providing a captivating glimpse into the watch’s mechanical heart. The leaf-style hour and minute hands, crafted from steel that matches the case, sweep gracefully across the dial, complemented by the heat-blued hands of the calendar complication indicators, adding a touch of classical flair.

The Complete Calendar Complication and User Interaction

Despite its name, "Annum," which might suggest an annual calendar function, the Haim Watch Company Annum is, in fact, a complete calendar watch. It presents a symmetrical display of four subdials, providing day, date, month, and moonphase information. This comprehensive display offers all the essential temporal data a watch enthusiast could desire. However, a key consideration at its price point of $2,149.99 is the nature of its calendar adjustment. The Annum is a manually adjusted complete calendar, meaning that months with fewer than 31 days require manual correction via recessed pushers located on the sides of the case. This is a common characteristic of complete calendars in this price bracket, distinguishing them from more complex annual or perpetual calendars that automatically account for varying month lengths.

The watch is supplied with a small adjuster tool for these pushers. However, as is often the case with such tools, the risk of misplacement is significant, particularly during travel. Many users, including the author, find that a simple toothpick serves as an effective alternative for these adjustments. The practical application of these pushers becomes apparent when considering the calendar’s need for manual intervention. Five months of the year – February, April, June, September, and November – will require adjustment if the watch is not continuously wound. For February, this includes accounting for leap years.

Setting the watch involves a specific sequence of pusher activations. The pusher on the top right of the case adjusts the month, while the pusher on the lower right adjusts the date. The pusher on the top left controls the day of the week, and the bottom left pusher sets the moonphase. It is crucial to observe the "danger window" for date adjustments, which Haim Watch Company advises is between 9:00 pm and 1:00 am. To avoid potential damage to the movement, it is recommended to set the time to approximately 6:30 before engaging any of the corrector pushers. This careful operation ensures the longevity and accuracy of the complete calendar mechanism.

Case Design and Wearability

The Haim Watch Company Annum impresses with its surprisingly compact dimensions, a deliberate design choice that enhances its wearability. The watch features a diameter of 38mm and a lug-to-lug measurement of 45mm, making it suitable for a wide range of wrist sizes. While its on-paper thickness of 12mm might suggest a substantial presence, the Annum wears considerably thinner than its specifications might initially indicate. This perception of slenderness is a result of several design elements. The double-stepped bezel, a smaller screwed-in caseback, and other subtle details contribute to the visual impression of a more slender midcase relative to its actual measurement.

The finishing of the stainless steel case is noteworthy for its price point, showcasing a pleasing interplay of polished and vertically brushed surfaces that interact dynamically with light. A particularly appreciated detail is the modern interpretation of the Cornes-de-Vache lugs, a classic design element that translates exceptionally well to the Annum’s contemporary aesthetic, contributing significantly to its comfortable and stylish wear on the wrist. These thoughtful design choices underscore Haim Watch Company’s commitment to creating watches that are not only mechanically interesting but also aesthetically pleasing and comfortable for everyday wear.

The Custom HWC-02 Caliber: A Microbrand Masterpiece

At the heart of the Haim Watch Company Annum beats the brand’s custom-designed mechanical caliber, the HWC-02. This movement is engineered to meet rigorous standards, with an accuracy regulation of +/- 10 seconds per day. The true value proposition of the Annum lies in the ingenious execution of its movement. Miah has masterfully integrated his proprietary calendar module atop a reliable time-only base movement sourced from the Miyota 9000 series. This strategic approach allows for the incorporation of complex functions without the prohibitive cost associated with in-house developed complications from scratch.

This type of innovative integration, reminiscent of the brand’s earlier Viajero model where a GMT movement was cleverly repurposed for worldtime functionality, is precisely what continues to capture the attention of watch enthusiasts and keeps the Haim Watch Company on the radar of discerning collectors. The "Fumé" dial, in particular, serves as an excellent showcase for this module, allowing wearers to appreciate the intricate mechanics visible beneath the smoked dial. Miah’s inspiration for this module draws from historical movements, and his journey to create it is a compelling narrative of problem-solving and dedication. The initial pursuit of NOS ETA 2890-9 movements proved unfeasible, prompting the development of this bespoke solution.

Movement Finishing and Thoughtful Details

The finishing of the HWC-02 caliber, visible through the exhibition caseback, reveals a thoughtful approach to detail that belies the watch’s price point. While the striping on the plates, though industrial in nature, presents a visually appealing aesthetic, the homage to a hand-engraved balance cock appears somewhat ambitious in its final execution. Nevertheless, these efforts contribute to a richer horological experience for the wearer.

A particularly engaging feature of the rotor is its innovative design. It incorporates a gold-colored weight affixed to a transparent disc, creating the visual illusion of a peripheral rotor. This element, along with other subtle design choices, offers delightful "easter eggs" for watch enthusiasts who appreciate the finer details of mechanical watchmaking. These elements collectively contribute to the Annum’s overall appeal, offering a compelling blend of complex mechanics, thoughtful design, and accessible pricing.
