First, check the model number on the caseback or paperwork: Timex’s controls documented for the Marlin Moon Phase TW2W51000 are not the same as the procedure in its general “Moon Phase Models” manual section. For TW2W51000, Timex says the moonphase register at 6 o’clock adjusts independently, but its product Q&A does not give a complete alignment sequence.
Check which Marlin Moon Phase you have
Find the model number on the caseback, paperwork, or product listing before moving the crown or pressing a button. The instructions below distinguish the TW2W51000 from Timex’s general moonphase-manual guidance; do not assume the latter applies to your watch unless its own manual confirms it.

Timex’s product Q&A describes these controls for this model:
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- Day of the week: Pull the crown out and turn it anticlockwise.
- Month: Press the pusher at 2 o’clock—the button above the crown—to advance the month.
- Main time and date/day wheel: Pull the crown fully out and rotate it to move the time and wheel through full revolutions.
- Moonphase: The register at 6 o’clock adjusts independently.
The Q&A does not explain the moonphase control’s exact movement or provide a calibration sequence for setting a particular lunar display. Because of that, these controls do not add up to a verified step-by-step moonphase alignment procedure. If the register’s adjustment is unclear, consult the manual linked from the product page for your exact watch or contact Timex support rather than treating the calendar controls as moonphase instructions.
What Timex’s general moonphase manual says
Timex’s general manual section titled “Moon Phase Models” says to pull the crown to the middle position (B), then turn it clockwise or counterclockwise until the correct moon phase appears. It says to return the crown to its normal position afterward and warns that wearing or storing the watch with the crown in the middle position can damage the movement. The manual also gives a separate full-out-crown procedure for setting the time.

If the display or controls do not match
- Recheck the model number rather than relying on the “Marlin” name alone.
- Use the manual linked to your exact product variant; crown positions and functions can differ between models.
- Do not leave the crown in a pulled-out position after setting. For the general manual’s middle-position procedure, Timex specifically says to return it to normal.
- If you cannot identify the independent moonphase adjustment or the indicated phase remains unclear, ask Timex for model-specific guidance instead of forcing the crown or pusher.
