Loresum

Loresum Watches is an independent watchmaking company, operating under Angel Jason Creative Company Limited and shipping from both the UK and Hong Kong, founded by designer Jason Chan around the mission of achieving a new standard in both aesthetics and mechanics. The brand's unusual name is drawn from 'lorem ipsum,' the placeholder text used throughout the design world to demonstrate a layout's visual composition without distracting content — Loresum takes that idea of pure aesthetic completeness as its founding philosophy, aiming to create original, artful watches whose beauty stands on its own. Chan brings genuine watch-industry pedigree to the project: his first brand, JW Watch, debuted in December 2017, and its JW-01 and JW-02 models became sufficiently sought-after that they remain out of stock to this day; he subsequently joined the Behrens Original team as a designer, where he worked within a mature development team and deepened his expertise in high-quality proprietary movement modules before founding Loresum. That philosophy carries directly into Loresum's production standard: the brand does not use pre-made parts sourced from the open market, developing its own bespoke modules — moonphase, regulator, jumping hour, and more — in-house, so that every mechanical detail aligns precisely with the brand's own aesthetic intentions rather than being constrained by an off-the-shelf component. Loresum's designs are also explicitly built around the golden ratio, drawing on that ancient mathematical principle of proportion to give each case and dial layout a considered, harmonious visual balance.

Loresum's early watches are regulators and module experiments built on the Miyota 9015. The LS01, The Railway Map, is a regulator inspired by Harry Beck's 1933 diagram of the London Underground: eight directional lines and circles ripple out from the centre, two rotating discs act as the station, a dotted marker on each disc's edge indicates the time, and the inner gears are left exposed. The LS02, The Golden Ratio, builds the regulator layout to golden-ratio proportions, with hours at the top, seconds in the middle and minutes below in a vertical line, a rotating gear for day and night, a date dial, and seven layers of exposed, platinum-plated gears. The LS03, The Wandering Moon, adds a moon indicator that works as a wandering hour, turning on a 31-tooth wheel over 31 days and slipping beneath the hour and minute discs, with an aventurine dial option; all three modules come from the factory behind Behrens Original. The J1 then moves to the Sellita SW200-1 with a large in-house jumping hour, a far bigger hour window than the subdial-sized discs on cheaper Seagull-based designs.

The LS04, The True Moonphase, is the signature: a genuine 29.5-day moonphase driven by a 59-tooth gear module, with the moon rendered as a mother-of-pearl cut-out bearing a 3D-printed lunar texture, set in a CNC mirror-polished frame on a rotating aventurine disc scattered with Super-LumiNova stars. Custom skeletonised hands form a spear-like shape where they overlap, and the 39.5mm case is 11mm thick including its domed sapphire. It runs on the Miyota 9015 (4Hz, 42-hour reserve) or, as an upgrade, the Swiss Sellita SW200-1 with a clockwise moonphase, and comes with aventurine, mother-of-pearl, and onyx dials. Two limited editions build on it: the Founder Edition Lunar Veil, limited to 20, which Chan first had the factory assemble for himself, with a frameless platinum-plated engraved moon under smoked glass so both moons stay visible; and the Moon Landing 55th, limited to 200, with a black onyx dial, a gold-plated moon bearing an astronaut's footprint, and a caseback engraved with Neil Armstrong's famous words. The LS04 V2 36.5 keeps the mechanism on a gold-plated Sellita SW200-1 as standard, with an enlarged moon aperture and dials the brand describes as cut from natural stone — aventurine, Eisenkiesel, bloodstone, or garnet — behind an exhibition caseback showing an engraved moon rotor, on an 18mm strap made with Hong Kong sustainable-luxury brand MONVES from Conceria 800 vegetable-tanned calf leather.

The LS05, the Double Moonphase, shows the moon as seen from both the Northern and Southern Hemispheres at once, with two moons on a single disc driven by a 59-tooth module developed with the Behrens factory; it pairs an aventurine glass chapter ring and diamond-cut trapezoid indices with the Miyota 9015 in a 39.5mm case 11mm thick, offered as Galactic Blue, Eclipse Black, and Royal Black. A Guilloché Limited Edition of 100 marked the brand's first handcrafted guilloché dial, in green with an aventurine ring and a rose-gold-plated case. The LS06, Royal Ellipse, turns to the 1970s with a 35.5 × 39.5mm ellipse case just 9.4mm thick around the HZ5000a micro-rotor movement, with small seconds and customised heat-blued screws. Each LS06 carries a large dial cut from natural stone — Charoite, Malachite, Tiger's Eye, Lapis Lazuli, or Onyx — in steel or rose-gold plating, on an Epsom-pattern Italian calfskin strap, with a bead-of-rice bracelet sold separately.

Loresum's Art Series draws on places that matter to the brand. The LS06 Adventures in Wonderland, a UK-inspired collaboration with Crown Hour limited to 150 pieces, has a white enamel dial printed with the White Rabbit, whose pocket watch is a working small-seconds display with playing-card suits as hour markers; it comes in a gold-toned case on a MONVES strap, with a themed box and deck of cards. The LS06 The Great Wave off Kanagawa, limited to 200, prints Hokusai's wave on a light-gold dial. The Moonlight Lion Rock, again with Crown Hour, honours Hong Kong, Chan's birthplace: a 38mm, 9mm-thick case holds a deep-blue aventurine dial, a dark Lion Rock relief at 6 o'clock made by multi-layer stamping and CNC machining, and the true moonphase at 1 o'clock on a Sellita SW200-1, limited to 200 pieces with 170 sold as of October 2026. Across the whole range, Chan's stated goal remains constant: to make historically rare, high-end complications — genuine moonphase, true micro-rotor winding, hardstone dials — accessible at a price point well below where major manufactures have traditionally placed them.
