Warranty

Each watch undergoes comprehensive servicing before shipping to ensure quality and performance. This includes a complete disassembly of the movement, restoration or replacement of parts as needed, thorough cleaning of the movement and case, precise reassembly to ensure all components function correctly, careful lubrication, accuracy adjustments, and a final power reserve check.

We offer a 1-year warranty for mechanical and automatic watches and a 6-month warranty for quartz watches.

Our warranty covers repair for the following faults:

• Issues with movement or electronic parts
• Movement malfunctions, including stopping, inaccurate operation, or problems with additional watch functions (e.g., automatic winding, calendars, stop seconds, chronograph)

The warranty is void if the product has defects from improper use, including but not limited to:

• Signs of impact or mechanical damage (e.g., dents, nicks, missing hands or parts, deformed case or crown, damaged buttons)
• Evidence of unauthorized opening or tampering outside an authorized service center
• Exposure to extreme temperatures (above +50°C or below -20°C)
• Internal or external damage from impact, shock, or applied force (e.g., cracked glass, deformed parts)
• Damage from moisture or water ingress (fogging or condensation on the inner watch glass)
• Contact with chemicals or solvents (e.g., alkalis, acids, solvents)
• Damage from foreign substances or objects entering the mechanism
• Any damage resulting from misuse or carelessness by the buyer

The following are not considered defects:

• Natural wear and tear on the case, crystal, buttons, crown, or strap
• Minor fogging on the inner side of the watch crystal
• Second hand deviation within 3° of scale markings
• Minor misalignment of hour and minute hands (up to 3°)
• Daily accuracy variation within ±90 seconds
• Battery depletion

If your watch develops a defect within the warranty period, please contact us at info@dumarko.com or through our contact form, including a description of the issue and any supporting photos or videos. We will provide instructions on how to proceed.

Warranty service is conducted exclusively at our authorized service center. After we confirm eligibility, you will need to send the watch to us, sharing the tracking information once shipped.

For approved warranty cases, return shipping to and from our service center will be free, and we will discuss options for reimbursing your initial shipping cost. If the issue is not covered under warranty, we will inform you of repair costs, and you can decide how to proceed.
