Masterclock warranty: 5-year coverage via Daylight

The Masterclock warranty is a standard 5-year limited warranty. What is included, what is excluded, and how does the process run via Daylight as authorised Masterclock distributor?

Choose your reading level

Every Masterclock device you buy through Daylight comes as standard with five years of warranty on parts and labour. That is exceptionally long in this segment, and the handling goes directly through Daylight as the official distributor, not via a detour through the United States.

The warranty covers material and manufacturing faults under normal use. It does not cover damage from misuse, lightning (if the antenna has no surge protection), transport damage or third-party modifications. A faulty device you send to Daylight; we arrange the repair or replacement. Unsure whether something is covered? Just ask, and we will look at it together.

Every Masterclock product supplied via Daylight bv comes standard with a 5-year limited warranty on parts and labour. That makes Masterclock one of the few brands in this segment with such a long standard warranty. What is included, what is not, and how does it work in practice?

What does the Masterclock warranty via Daylight cover?

Material defects in all components, motherboard, power supply, display modules, etc.
Manufacturing defects under normal use in line with the datasheet and manual
Repairs or replacement by Masterclock within the warranty period
Service via Daylight bv as authorised Masterclock distributor, a direct line, no escalation via the US

What is not covered by the warranty?

Damage from incorrect use (wrong voltage, no earthing, moisture, physical damage)
Lightning damage if the antenna installation has no gas-discharge arrestor (a common cause of defects)
Hardware modifications by third parties
Consumable parts: rubber feet, battery replacement for real-time-clock ICs after 7 years
Transport damage: covered by the carrier and its insurance, not by warranty

What is the difference between carry-in and on-site warranty?

Masterclock's warranty is carry-in by default: you send the faulty unit to Daylight, we send it on to Masterclock (USA) or carry out the repair here if that is feasible.

No mandatory on-site service, but for customers with SLA requirements we can offer a service contract in which Daylight supplies a replacement unit within 24–48 hours while the repair is under way. Discuss this before purchase, as it is a separate SLA alongside the warranty.

In practice: how do I report a fault?

1. Call or email Daylight support with the serial number plus symptoms 2. We first run a remote troubleshoot, often it is a config issue or firmware issue resolved without shipping 3. If hardware replacement is required: an RMA number is requested from Masterclock and we send you the shipping instructions 4. Repair/replacement via Masterclock, average turnaround 2–4 weeks (depending on model and complexity) 5. Unit back with you, tested, with a certificate of conformance

Long term — what after 5 years?

After the warranty period we offer paid repairs via Daylight. Most Masterclock products last 10–15 years under normal use. However: GNSS antennas age more quickly (UV degradation on the roof), Rubidium cells live 10–15 years before they "go".

In practice via Daylight

In 35 years of Masterclock product we have seen a handful of genuine hardware defects, mostly power supply or antenna cable. The overwhelming majority of support tickets are configuration, not broken hardware. Call Daylight support before you ship.

From theory to practice: browse the Masterclock products in the Masterclock range from Daylight.

The standard coverage is a limited warranty of five years on parts and labour under normal use in accordance with the datasheet and manual. Handling runs via Daylight bv as official distributor, which shortens turnaround compared with a direct RMA to the manufacturer.

Exclusions follow the usual line: incorrect supply voltage, missing earthing, moisture, physical damage, third-party interventions, and consumable parts. Two things are underestimated. First, lightning and surge damage: a GNSS antenna on a roof is a strike point; without a gas-discharge arrestor in the coax, consequential damage generally falls outside coverage. Second, transport damage, which falls under the carrier and its insurance, not the product warranty, and which you must therefore establish immediately on delivery.

The regular handling is carry-in: the device goes to Daylight, which carries out repair here where possible or forwards it to the manufacturer. Keep the purchase date and serial number; these determine the warranty term.
