Setting the Standard for Trust in Luxury Watches

Guaranteed Authenticity

Trust is everything in the world of luxury watches. At Investment Watches, every timepiece we handle is backed by a commitment to absolute authenticity and long-term confidence.

Authentication

All watches are thoroughly inspected by our in-house team of expert watchmakers and specialists. Each timepiece undergoes a detailed, multi-point evaluation covering the movement, case, dial, hands, and overall condition. We combine traditional horological expertise with modern verification tools to ensure every detail is correct and consistent with the original manufacturer’s specifications.

As an official authentication center for Grailzee, we operate at the highest industry standards, handling a significant volume of watches with precision, consistency, and accountability.

Our process is independent and unbiased. We do not rely on third-party assumptions or external sales incentivesβ€”our reputation is built entirely on accuracy and trust.

Authentication Certificate

Every watch sold or authenticated by Investment Watches includes a formal Authentication Certificate. This document verifies the watch’s authenticity and outlines key details such as the reference number, serial range when applicable, movement, and any relevant notes regarding condition or originality.

This certificate supports resale, insurance, and long-term ownership with full transparency.

Warranty

All watches sold by Investment Watches are covered by a one-year mechanical warranty unless otherwise stated. This warranty ensures that the watch functions as intended under normal use.

The warranty covers mechanical issues related to the movement. It does not cover damage caused by water, misuse, accidents, or normal wear and tear. Vintage watches, generally those manufactured before 1990, may be excluded due to the nature and availability of original parts.

If a watch remains covered by the original manufacturer’s warranty, that coverage will apply in addition to our own.

Five-Year Authenticity Guarantee

Investment Watches stands behind the authenticity of every watch we sell or authenticate. Each timepiece is covered by our authenticity guarantee for five years from the date of purchase or the date shown on the Investment Watches Authentication Certificate, as applicable.

During this five-year period, we guarantee that the watch is authentic and consistent with the authenticity findings documented at the time of our inspection. This guarantee applies to the watch in its original authenticated condition and does not cover any parts, alterations, or modifications made after the watch leaves our possession.

Secure Handling

All watches are handled and stored in professional facilities with advanced security systems, including bank-grade vaults. From intake through delivery, every step is designed to protect both the watch and the client.
