Automatic watch FAQs: choosing your model
Which Mercier automatic watches cost under $1,000?
Manx and Manx Meridian are $795; Passage GMT is $825. All three have sapphire crystals and automatic movements. Choose Manx for day and month indicators, Meridian for an additional 24-hour indication, or Passage for its independently adjustable local hour hand.
Are Manx calendar subdials the same as a chronograph?
No. Manx uses a Miyota 9122 to display the day and month; its subdials do not time elapsed seconds. Manx Meridian uses a Miyota 9120 with day, month, 24-hour and date functions. Its 24-hour indication is not the same feature as Passage's independently adjustable local hour hand.
What makes the Manx design distinctive?
The 42mm black PVD case frames calendar subdials beneath a domed sapphire crystal. Noir pairs a black ceramic dial with champagne markers; Blanc pairs a white ceramic dial with contrasting black subdials. Each caseback is individually numbered.
What does an individually numbered watch mean?
Each Manx has its own serial number engraved on the caseback. It identifies the individual watch; it is not a promise of investment value or future resale price. Keep that number with your order details for service and warranty questions.
What is Manx?
An everyday-luxury automatic watch from Mercier Prototype, Belgian-designed, veteran-owned, and individually numbered, with a Japan-made automatic movement.
Is it automatic or quartz?
Fully automatic. It runs on a self-winding Miyota Cal. 9122 with a roughly 42-hour power reserve, no battery.
What size is the case, and will it fit me?
42mm diameter, 51mm lug-to-lug, on a 22mm strap. It wears true to size, and the strap comes in two lengths: Standard fits 6.5–7.3 inch wrists, Extra Large fits 7.5–9.1 inch wrists — if you are between sizes, choose Extra Large.
Is it water resistant?
Yes, 10 ATM, fine for everyday wear, swimming and snorkeling, though not deep-sea diving.
What crystal does it use?
A domed sapphire crystal with anti-reflective coating, set in a 316L steel case finished in black PVD.
What dial options are there?
Two: the Noir, a blacked-out dial, and the Blanc, a crisp white dial. Both share the same case and movement.
When does Manx ship?
Manx is in the final assembly stage of production and ships in late December. The first run is capped and individually numbered.
Can I pay over time?
Yes, Affirm, Klarna, Afterpay and Cash App Pay are available at checkout, alongside card, Apple Pay and Google Pay.
How does the $200 reservation deposit work?
Not ready to pay in full? Reserve your Manx — and your individually assigned serial number — with a $200 deposit. It's credited in full toward the $795 price, and the $595 balance must be paid before your watch ships. The deposit is fully refundable any time before shipment, and transferable between colorways.
Do you offer a military or first responder discount?
Yes, 10% off for active and veteran military, first responders, and law enforcement, verified through ID.me / GovX. Once verified you'll receive a single-use code to enter at checkout. Contact us if you need a hand.
Is checkout secure?
Yes. Payments are processed securely by Shopify checkout — Shop Pay, Apple Pay, Affirm, Klarna & more. We never see or store your card details.
Can I cancel my order?
Yes. You can cancel any time before it ships for a full refund.
Where do you ship?
We currently ship within the United States only. We hope to open up international shipping down the road, email us if you'd like to be kept posted.
How much does shipping cost, and is there tax?
Shipping is free within the United States, and every order is tracked and insured to your door. Any applicable sales tax is applied when your order ships.
What is your return policy?
Return within 30 days of delivery for a refund or exchange, in like-new condition with the box and numbered papers. See Return Policy.
Can I exchange dials?
Yes, we're happy to swap Noir for Blanc, or the reverse, subject to availability.
What does the 5-year automatic watch warranty cover?
Every Mercier has a 5-year limited warranty against manufacturing and movement defects. Normal wear, accidental damage, misuse and unauthorized service are excluded. Read the full warranty coverage and exclusions before ordering.
How do I make a warranty claim?
Email Devin@mercierprototype.com with your order number and the serial number engraved on the caseback.

Who makes Mercier Prototype?
