GP Annual Calendar - Annual Calendar, Moonphase, Analog-Digital, Japanese Quartz, 43mm
The Daniel Gorman GP Annual Calendar is a 43mm complication quartz watch featuring an annual calendar, moonphase display, and analog-digital hybrid dial - three features that together create a watch that does far more than display the time. The annual calendar requires date adjustment only once per year (at the February-March transition); the moonphase tracks the lunar cycle; the analog-digital display combines hands and digital elements on the same dial. 316L stainless steel case, sapphire crystal, 5 Bar / 50M, silicone strap, 43x51mm. Available in Blue, Black, Green, Silver Blue, Silver Black, and Silver Brown.

Annual Calendar
An annual calendar mechanism tracks the calendar across months of different lengths, requiring manual date correction only once per year - at the end of February, since the calendar does not account for the shorter 28/29-day month. For the remaining 11 months the date advances correctly without manual correction. In mechanical watchmaking this is a significant complication; in quartz it requires purpose-built calendar circuitry rather than a simple date wheel. The GP Annual Calendar delivers it on Japanese quartz in an accessible package.
Moonphase Display
The moonphase complication shows the current phase of the lunar cycle via a rotating disk visible through an aperture on the dial, typically depicting the moon against a starfield. A lunar cycle averages 29.53 days; the moonphase disk approximates this rotation mechanically. The moonphase is one of the most visual and romantic complications in watchmaking - at its most accurate in astronomical instruments, at its most beautiful in a well-designed dial aperture. On the GP Annual Calendar the moonphase sits alongside the annual calendar and analog-digital display in a multi-complication layout.
Analog-Digital Hybrid Dial
The analog-digital display combines analogue time indication (hands showing hours and minutes in the traditional way) with digital display elements on the same dial. The combination allows time-related information to be distributed between analogue and digital zones - hands for the primary time reading; digital elements for calendar data, day, or secondary displays. This hybrid presentation creates a more complex and technically expressive dial than either format alone.
Six Colour Variants
Blue, Black, Green: the primary dial colour options in the range's base tones. Silver Blue, Silver Black, Silver Brown: the Silver prefix indicates a lighter, more metallic-toned dial background with the secondary colour as the accent or sub-register tone. Silver Brown is the most distinctly warm and formal-reading variant; Silver Blue the most contemporary. All six share the same movement, case, crystal, and strap specifications.
Annual Calendar and Moonphase in a Quartz Watch
The annual calendar and moonphase are complications traditionally associated with high-end mechanical watchmaking, where the difficulty and cost of implementation in a mainspring-powered movement create a price premium. In a quartz platform the same information can be delivered via dedicated circuitry at a fraction of the cost of mechanical implementation. The result is a watch that displays the same data - annual calendar, moonphase, time - in a much more accessible price bracket. The tradeoff is the absence of the mechanical movement; the gain is daily accuracy far exceeding a mechanical equivalent and complete freedom from winding or reserve management. For the wearer who wants the visual richness of multiple complications on the dial without the price of a mechanical equivalent, the GP Annual Calendar is the directly practical answer. The six dial variants span from the composed and formal (Silver Brown, Silver Black) to the more contemporary and bold (Blue, Green), giving each buyer a colour-based entry point that suits their aesthetic without changing any of the functional specifications.
Available in Blue, Black, Green, Silver Blue, Silver Black, Silver Brown. Backed by Wclocks 1-year warranty.
Wear It For
The triple-complication quartz suits collectors, formally dressed occasions, and informed watch gift contexts.
Complication Enthusiasts
For collectors who want annual calendar and moonphase on the wrist without the price point of mechanical equivalents, the GP Annual Calendar provides both complications in one dial. The three-display layout (annual calendar + moonphase + analog-digital) creates a complex and information-rich dial presentation uncommon at this price.
Business Dress and Smart Formal
At 43mm on a silicone strap the GP Annual Calendar reads as a substantial dress-complication watch. Silver Black and Black are the most business-formal dial configurations; Silver Blue and Blue are more contemporary but still dress-appropriate. The multi-complication dial creates conversation in business contexts among informed observers.
Gift for Watch Enthusiasts
An annual calendar and moonphase on sapphire crystal is a gift that demonstrates understanding of watchmaking beyond the basics. For a recipient who follows horology, the GP Annual Calendar is a considered and specific choice. For a recipient new to watch collecting, it is a compelling introduction to complications as a concept.
Multi-Occasion Daily
Silicone strap and 5 Bar water resistance make the GP Annual Calendar robust enough for daily wear across all conditions. The annual calendar means minimal ongoing adjustment - once correctly set it reads accurately across the whole year except for the February-March correction. The moonphase adds a daily visual interest element that purely time-displaying watches cannot offer.

Frequently Asked Questions
What is an annual calendar watch?
An annual calendar automatically tracks the date across months of 30 and 31 days, advancing correctly without manual adjustment for 11 months of the year. The only manual correction required is at the end of February, when the calendar cannot automatically account for the 28 or 29-day month. On a standard date watch the date must be corrected at the end of every short month; an annual calendar reduces this to once per year. It is a meaningful practical complication for daily wearers who dislike frequent date corrections.
How does the moonphase display work?
The moonphase display shows the current phase of the lunar cycle via a rotating disk visible through an aperture on the dial. A full lunar cycle averages 29.53 days. The moonphase disk makes one full rotation over approximately 59 days (two lunar cycles shown on a standard 29.5-tooth gear), displaying the moon graphic moving from new to full to new again. Over time the quartz-driven moonphase accumulates small discrepancies from the actual lunar cycle; correction is needed once every few years or months depending on implementation. The primary value is aesthetic and ceremonial - the moonphase aperture is one of the most beautiful dial elements in watchmaking.
What is the analog-digital display?
The analog-digital hybrid dial combines conventional analogue time display (rotating hands for hours and minutes) with digital elements on the same dial. The digital elements may show calendar data, day of week, or secondary time information in numeric form. The combination creates a more information-dense and visually complex dial than either format alone and is associated with certain haute horlogerie and sport-luxury watch design traditions.
Does it use a battery?
Yes - Japanese quartz movement, battery included and ready to wear. Quartz accuracy is significantly better than mechanical equivalents; the movement will not require winding. Battery replacement intervals depend on the specific quartz module but typically range from 1 to 3 years for multi-function quartz displays.
What crystal is used?
Sapphire crystal - the same scratch-resistant crystal used in high-end mechanical watches. Sapphire is significantly harder than Hardlex or standard mineral glass, providing long-term scratch resistance that preserves dial visibility indefinitely under normal daily wear. It is one of the best specifications on this watch relative to its price point.
How do I choose between the six colour variants?
Blue, Black, Green are primary solid dial tones - Blue is the most contemporary; Black the most formally versatile; Green the most distinctive. Silver Blue, Silver Black, Silver Brown have a lighter metallic-tone dial background with the secondary colour as the accent - Silver Brown is the warmest and most formal-leaning; Silver Black the most professional; Silver Blue the freshest. All six have identical specifications; the choice is purely aesthetic.
What is the water resistance?
5 Bar / 50M - suitable for daily wear, hand washing, rain, and everyday moisture exposure. Not rated for swimming or diving. Appropriate for a dress-complication watch intended for formal and professional daily wear.
