FAQs
Does this watch need a battery replacement?
No, the Promaster Land GMT features an Eco-Drive movement, which is powered by light. It recharges automatically and does not require traditional battery changes.
How long does the charge last if I don't wear it?
A fully charged Eco-Drive watch can typically run for several months (often 6 months or more) in complete darkness, depending on the specific model and reserve capacity.
Can I swim with this watch?
Yes, with 200-meter water resistance, this watch is suitable for swimming, snorkeling, and even recreational diving. Ensure the crown is securely pushed in before water exposure.
How do I set the GMT hand?
The method for setting the GMT hand varies by model. Generally, you pull the crown out to a specific position and turn it to adjust the GMT hand independently of the main hour and minute hands. Refer to your product manual for precise instructions.
Is the anti-reflective coating on the crystal durable?
The sapphire crystal itself is very durable and scratch-resistant. The anti-reflective coating enhances legibility but can be susceptible to micro-scratches over time with heavy use. Clean gently to preserve it.
What is the lug width for strap replacement?
The lug width for the Promaster Land GMT 39mm is typically 20mm. Always confirm with the product manual or by measuring if considering a replacement strap.
Troubleshooting
Watch stopped or losing time
The Eco-Drive power reserve may be depleted. Expose the watch to a bright light source for at least 8 hours to recharge. If the issue persists after full charging, the capacitor might need service.
Date is incorrect
Pull the crown out to the time-setting position and adjust the date. Ensure you are not setting the date between 9 PM and 3 AM, as this can damage the date-setting mechanism. If it is within this window, advance the time past 12 AM to set the date correctly.
GMT hand is not correct
Consult the specific instruction manual for your Promaster Land GMT model. Typically, the GMT hand is set separately from the main time using a specific crown position or sequence. Ensure it is set to your desired reference time zone.
Scratch on the crystal
While sapphire is highly scratch-resistant, deep impacts can still cause damage. Minor scuffs may not be visible under normal light. For significant scratches, professional polishing or replacement by an authorized service center is required.

Setup, Compatibility & Care
Initial Setup:
- Charging: Expose the watch to a light source (natural or artificial) for several hours to ensure the Eco-Drive capacitor is fully charged if it has been stored in darkness.
- Time Setting: Pull the crown out to the appropriate position (usually the outermost position for time and date, or a specific position for GMT hand adjustment). Set the local time, date, and GMT time.
- GMT Hand: If the GMT hand needs to be set independently, consult the specific manual for your model, as it often involves a specific crown position or sequence.
Compatibility:
- This watch is a standalone analog timepiece and does not require pairing with other devices.
- It is compatible with standard watch bands if you wish to replace the original strap, provided they are 39mm lug width compatible.
Care Instructions:
- Cleaning: Rinse the watch with fresh water after exposure to saltwater or chlorine. Clean the case and crystal with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Water Resistance: Ensure the crown is pushed fully in before exposing the watch to water. Regular checks of seals may be advisable if heavy water use is expected.
- Storage: While Eco-Drive is self-sustaining, prolonged storage in complete darkness can deplete the charge over time. Occasional light exposure is recommended.
