The Timex Marlin Moon Phase TW2W51000 brings a genuine astronomical complication to the vintage-inspired Marlin line — a moon phase indicator tracking the lunar cycle, set against a striking green dial. The 40mm stainless steel case and brown leather strap keep the styling classic, so the watch reads as a considered dress piece rather than a novelty, even with the moon in the middle of it.
Rather than just hours and minutes, the TW2W51000 tracks the lunar cycle on the dial — the moon phase display moves through its cycle over roughly 29.5 days, showing you at a glance where the moon is in its cycle. It's a genuine complication, not a printed graphic, and it's what turns this from a standard Marlin into a talking point on the wrist. Combined with the green dial, it's one of the more distinctive references in Timex's current line-up.
The green dial is the watch's signature — bold enough to stand out, calm enough to still read as a dress watch. Luminous hands and markers keep it legible as the light fades, useful given how often a moon-phase watch gets worn into the evening. The 40mm stainless steel case is a versatile, wear-anywhere size, finished to suit both casual outings and more formal occasions.
A genuine brown leather strap with an adjustable buckle complements the case and softens with wear over time, giving the watch a warmer, more classic look than a steel bracelet would. Inside, a quartz movement keeps things simple and accurate day to day, with no winding required.
Rated to 30 metres (99ft), the watch handles rain, splashes and brief accidental immersion comfortably for everyday wear. It is not designed for swimming or showering, and as with any leather-strapped watch, prolonged water exposure should be avoided regardless of the case rating.
