Daily rate
The movement’s gain or loss, expressed in seconds per day, under the recorded test conditions.
s / dayWhy work with us
A movement’s journey does not end at manufacture. We check its performance, review the results and prepare it for dispatch with care. Throughout, you have a direct point of contact for clear answers and practical support.

01 / Performance, recorded
We assess timing performance alongside practical operation and visual condition. Results are reviewed against our acceptance criteria for the calibre and its test conditions.
The movement’s gain or loss, expressed in seconds per day, under the recorded test conditions.
s / dayThe balance’s swing, measured in degrees and assessed with the winding state and test position in mind.
degreesThe difference in time between the two halves of the balance’s oscillation, expressed in milliseconds.
msHow the rate changes between horizontal and vertical positions, helping us assess consistency.
s / dayObserved running duration, reviewed against the specification of the selected calibre.
hoursVisual condition, hand and crown operation, operating noise, and winding or calendar functions where applicable.
inspectionTiming readings depend on winding state, position, instrument settings and test conditions. The certificate records inspection results; final performance in a completed watch also depends on casing and assembly.
02 / Our release decision
A movement that does not meet our standard is held back. Where appropriate, it is calibrated and tested again. If it requires work by the manufacture, it is returned for correction and checked again before release.

03 / Evidence with your movement
Every movement is supplied with an individual Meridian Calibre quality-control certificate, documenting its inspection results and review.
It gives you a clear record of the movement supplied: its calibre and movement identifier, timing measurements, power-reserve observation, applicable functional checks and inspection details.

04 / The Meridian difference
Ordering through Meridian adds a documented inspection and release stage between production and your workbench, together with the service to guide your enquiry, coordinate corrective work and keep the conversation clear.
An individual certificate makes the inspection visible, with results specific to the movement supplied.
If a movement falls short, we manage calibration or its return to the manufacture and arrange the follow-up checks.
From selecting a calibre to an after-sales question, Meridian is your point of contact. We coordinate with the manufacture so you have a clear route to answers and follow-up.
05 / Service & communication
Choosing a movement involves more than a reference number. We take time to understand what you are building, explain the available options and clarify what still needs confirmation.
Talk to us about your projectWe discuss your requirements, share available specifications and fitting drawings, and set out the quotation in writing. Availability, customisation and timing are clarified for your chosen calibre and quantity.
We coordinate with the manufacture and keep you informed about progress, questions that need your input and any changes affecting the agreed plan.
Come back to us for inspection records, delivery questions or after-sales enquiries. We follow up with the people involved and explain the next steps.

06 / The final check
Packaging is part of our quality process. We check the movement, its accompanying documentation and its protective packing before dispatch, giving preparation for the journey the same attention as the inspection itself.
From the movement to the paperwork to the parcel, every part of the handover matters.
Fine finishing
The same calibre as manufactured and after finishing by Memorigin: as it leaves the production line, and after hand-finishing in Hong Kong.


The direction and pattern of the striping is changed to suit your design.
The standard gilt rotor became black here; other colours, and your logo, are available.
Every bridge edge is chamfered and then polished, so it catches the light the way fine watchmaking should.
Each screw head is individually finished.
Finishing is optional and quoted per design.
Made yours
Your logo on the rotor. Your wording engraved on the bridges. Striping and finish colour to your specification. The movement carries your brand; neither of ours appears on it.
Hong Kong
Every calibre with photographs, specifications and a fitting drawing you can send straight to your case maker.
One person answers your enquiry, your quotation and your questions, in your working day.
Prices on request, quoted per calibre and per order, valid for 60 days.
Order one or two, case them up, then decide.
Memorigin finishes movements and builds complete tourbillon watches; you deal with one supplier from the calibre to the watch.
12 months against manufacturing defects, spare parts for five years, claims handled by us.
Our watch house
Our watch house, Memorigin, has designed and built tourbillon watches in Hong Kong around calibres from this range since 2011. Three of its references — each opens on Memorigin’s own site.
