The movement inside This reference is built with either calibre. The choice changes the price, the rate and the reserve — nothing else about the watch.
| Base | Seiko NH35 or Miyota 8215, automatic | Swiss clone of the maison's own calibre |
|---|---|---|
| Rate | ±15 to 25 seconds a day | ±5 to 10 seconds a day |
| Reserve | About 40 hours | 55 to 70 hours |
| Balance | 21,600 A/h · six beats a second | 28,800 A/h · eight beats a second |
| Servicing | Any watchmaker can service it; parts are everywhere | Serviced by a specialist; finished as the original is |
| Suited to | Wearing daily, keeping simply, spending less | Matching the reference exactly, and glass casebacks |
The Swiss movement is $50 more. That figure buys the rate, the reserve and a movement that reads correctly through a glass back — not a different watch.
Which we would take. If it is to be worn every day and serviced down the road from you, the Japanese is the honest answer. If it has to survive a loupe against the reference — or the caseback is glass and the movement is meant to be seen — take the Swiss.
The exact base calibre for this reference is confirmed in writing, with the QC film, before anything is dispatched. The two movements, explained
- Ships from the USA

Add to cart, enter your ship-to details, then pay with crypto — or message the desk (replies typically within a few hours, Pacific business hours). QC film usually same day after payment clears — reply GL to ship or RL for another. Japanese +$50 · Swiss +$100.

Description
HK Factory Longines Ceramic Conquest L3.784.4.56.9 makes its grand debut, a limited edition full ceramic "Longines"! The ultimate trendsetter of the fourth quarter of 2022, the chosen one, exclusive 43mm size, original mold tooling, full of sincerity!
All the way through, the Longines family's Dark Side of the Moon
1. Case: Adopting a brand-new design, the one-piece full ceramic case will never fade and has no metal inner liner, making it more textured, without abnormal noise, and free of impurities.
2. Mirror surface: Ultra-thick, ultra-durable and wear-resistant synthetic sapphire material, double-sided multi-layer polishing restores the mirror surface's transparency and resists light reflection.
3. Size: Perfectly replicates the 43mm watch body, recreating the original thickness, with meticulous attention to detail.
4. Handle: The handle adopts a ceramic + black steel embedded handle, which is stronger, more wear-resistant and scratch-resistant, and the top of the handle is laser-engraved with the Longines logo.
5. Case back: The case back features a sealed design with ceramic CNC three-dimensional engraving, employing the rigorous craftsmanship of replicating the original. The matte case back is adorned with a circular satin finish, and each component presents a different texture, showcasing the diverse style of this diving watch. It boasts a water resistance depth of up to 300 meters.
6: Bezel edge: Made with imported diamond grit and repeatedly polished and brushed, making the bezel edge more delicate. The scale is made with PVD vacuum electroplating, which makes it smoother. The bezel edge is tight and flawless when rotated in one direction.
7: Movement: The Seagull 2824 movement (28,800 vibrations per hour) perfectly ensures the stability and smoothness of the L888's automatic winding mechanism, and is a boon for audiophiles who appreciate Swiss movement. Whether it's the Seagull movement or the Swiss movement, both offer excellent value for money, and the closed sole design is perfectly acceptable!
HK has spared no expense in improving quality and meticulously crafted every detail to achieve its unique style. We welcome all connoisseurs to appreciate and enjoy our products!
