At Mazzo, transparency and precision are part of our promise. Below is exactly how we build, verify, and deliver every watch, so you know what to expect at every step.

Design, Build & Assembly

Our Mazzo watches are in-house assembled by our team in Canada. Where applicable, components and movements are Swiss manufactured; final assembly and hand regulation are completed at our workshop to ensure each watch meets the most precise accuracy standards.

Every Mazzo watch ships in our signature presentation box, complete with a protective travel case, certificate of authenticity, serial registration, and a 5 year Warranty card with NFC

Timing: Made to order builds (Signature, Fusion, Sportivo) are assemble, engraved and tested prior to shipping. Please allow up to 12 business days from order confirmation for assembly, regulation, and final inspection. Some limited editions and orders with custom engravings requested, may take longer than expected.

Seiko Mod's

Each Seiko mod available through Mazzo Watches is a custom built piece assembled with authentic Seiko movements and selected high quality aftermarket components.
While inspired by iconic designs, these watches are not affiliated with or endorsed by Seiko or any other brand.

Every mod is assembled on demand, built only once your order is confirmed.
Our watchmaker test, regulate, and seal each piece before shipment to ensure the best possible accuracy and reliability.
Production and quality control take up to 10 business days prior to shipping.

Certified Pre-Owned Authentication

Every certified pre-owned watch is inspected by our experts and independently authenticated. The authentication process includes:

• Visual and serial verification

• Movement inspection and functionality testing

• Time regulation and service as required

• Final cosmetic and water-resistance check (when applicable)

Timing & Guarantee: Authentication and preparation for shipment are completed within 3 business days from receipt of the watch at our facility. If we cannot ship your certified pre-owned purchase within 3 business days, a full refund will be issued automatically to the original method of payment.

Regulation & Quality Control

Before leaving our workshop every watch undergoes hands on regulation and a final quality checklist:

• Accuracy test and regulation targeting the most accuracy readings of ±s/day.

• Water resistance test (for applicable models)

• Visual inspection for finish and fit

• Packaging, serial registration, and inclusion of documentation, warranty card (NFC) in Mazzo Collections

Our goal: every Mazzo wristwatch should arrive ready to wear and keep time reliably.

Returns & Refunds

• If a certified pre-owned order cannot be authenticated and shipped within 3 business days, we refund 100% to the original payment method.

• Each Mazzo watch is assembled to order and inspected individually before shipping.
  Because these pieces are built specifically for each client:

  • Cancellations are accepted only within 24 hours of purchase.

  • Once the assembly process has begun, orders cannot be canceled or modified.

  • Returns are only accepted in cases of manufacturing or assembly defects covered under our Mazzo Warranty.

  • If a warranty claim is approved, we will repair, rebuild, or replace the watch at no additional cost.

  We cannot accept returns for preferences such as color, size, or design changes once the order has entered production.

• Each Seiko Mod is a custom assembly using authentic movements and selected components, built exclusively per order.

  Refunds or returns are not available once assembly has started.

  If a mod arrives with a clear defect or assembly issue, please contact us within 3 business days of delivery for evaluation.

• Verified defects will be corrected under the 12-month Mazzo Warranty, including free repair or replacement at our discretion.

Shipping & Communication

• We’ll email you an estimated ship date when your order is confirmed and notify you again when the watch ships (tracking included).

• Expected ship time is shown on every product page, we recommend checking that field before purchase if timing is critical.

Final note on accuracy & trust

We regulate every movement in-house and visually verify every detail. This hands-on approach helps us deliver consistent accuracy and gives you confidence in every Mazzo watch you own.
