Introduction
In a market saturated with heritage reboots and safe-bet divers, Studio Underd0g has carved out a niche that feels both refreshing and irreverent. The brainchild of British designer Richard Benc, the brand launched in 2020 with a mission to inject colour, character, and a healthy dose of humour into the affordable mechanical watch segment. The Full Mo0n (ref. 02BEBR_M) is their take on the classic moon phase complication—a complication often reserved for dress watches costing five figures. Here, it’s delivered with a playful twist: a bright blue ‘moon’ disc that looks like a cartoon celestial body, complete with craters and a cheeky expression.
But don’t let the whimsy fool you. Under the hood, this is a serious tool for the wrist. The 40mm stainless steel case is brushed and polished with a vintage-inspired profile, while the manual-wind movement offers a satisfying daily ritual. For the trust-fund-baby buyer who already owns a Patek or Lange, the Full Mo0n is a conversation starter—a watch that says you don’t need to spend a fortune to have taste. For the enthusiast on a budget, it’s a gateway into complications without breaking the bank. Let’s dive into the data.
Manufacture History
Studio Underd0g was founded in 2020 in the United Kingdom by Richard Benc, a graphic designer turned watchmaker. The brand’s ethos is simple: make watches that are fun, affordable, and mechanically interesting. The Full Mo0n is part of the ‘02’ series, which explores classic complications like moon phases and chronographs in a modern, accessible format. The brand has quickly gained a cult following among young collectors who appreciate its irreverent naming and bold dials.
Movement
The Full Mo0n is powered by the Seagull ST2553, a manual-wind movement with a moon phase module. This Chinese workhorse runs at 21,600 vph, has 21 jewels, and offers a 40-hour power reserve. It’s not COSC-certified, but it’s well-finished for its price point, with perlage and blued screws visible through the display caseback. The moon phase is set via a recessed pusher on the case side—a common solution at this price. Accuracy is typical for the caliber: +15 to +25 seconds per day. The moon phase itself drifts about 2.5 days per month, so you’ll need to adjust it every few weeks if you’re a stickler.

- Thickness: 12.5mm
- Lug-to-lug: 48mm

Wrist Feel
On the wrist, the Full Mo0n wears surprisingly compact for a 40mm case. The 48mm lug-to-lug keeps it from overhanging on average wrists, and the 12.5mm thickness is well-proportioned for a manual-wind moon phase. The leather strap is supple out of the box, though some may swap it for a NATO or a more premium option. The crown is signed and easy to grip for winding—a daily ritual that becomes oddly satisfying.
The weight is light enough for all-day wear, but the domed sapphire crystal and polished bezel give it a dressy sheen. It’s not a tool watch, but it’s robust enough for casual office or weekend wear. The moon disc is the star: a bright blue sphere with a smiling face that catches light and draws comments. It’s a watch that invites interaction.
Accuracy
Expect +15 to +25 seconds per day out of the box, typical for the Seagull ST2553. Regulation can improve this, but for the price, it’s acceptable. The moon phase mechanism is accurate to about 2.5 days per month—not COSC, but charmingly analogue.
Occasions
The Full Mo0n is a versatile piece. It works as a daily driver for the office, a casual weekend companion, and even a dress watch for less formal events. The playful dial might not suit black-tie, but it’s perfect for a dinner date or a night out.
Wrist Presence
4/5 – The playful moon disc and vibrant blue dial ensure it stands out without being obnoxious. It’s a conversation piece that still reads as a proper watch.
Reference Variants
Currently, the Full Mo0n is available in a single reference: 02BEBR_M with a blue dial and blue leather strap. Limited editions may appear in the future, but the standard model is the one to get.
Family References
The 02 series also includes the Panda chronograph (02BEBR_P) and a green dial variant (02BEBR_G) that was a limited run. The 01 series features chronographs with different colourways.
Other Notable Models by Studio Underd0g
Beyond the 02 series, Studio Underd0g offers the 01 series chronographs (e.g., the ‘Panda’ and ‘Reverse Panda’) and the 03 series field watches. All share the brand’s playful design language and affordable pricing.

Hold recommendation: This is a fun, affordable piece meant to be worn, not flipped. Limited editions may appreciate slightly, but the standard Full Mo0n is a depreciating asset. Buy it for the smile, not the ROI.
