How the movement and moonphase module work together
The watch uses a Sellita SW220-1 automatic base movement with Christopher Ward’s JJ04 moonphase module. The brand’s specification sheet describes it as a “Self-winding 26 jewel movement with ‘JJ04’ in-house Moonphase module.” The base calibre provides the automatic timekeeping movement; the added module drives the moonphase display.

Christopher Ward says that, if kept constantly wound, the moonphase indication will remain accurate for 128 years. That is the manufacturer’s claim about the moonphase display—not a statement that the watch keeps time to a particular daily rate for that period, nor an independently verified test result.
What the dimensions mean for fit
A 37 mm diameter gives the case a relatively compact stated width, but diameter alone does not determine how a watch wears. The 44.07 mm lug-to-lug measurement helps indicate how far it spans across the wrist, while the 13.10 mm height matters for how far it stands above it. Those numbers are more useful together than diameter alone when comparing the watch with one you already wear.

The listed case weight is 52 g. The sheet specifies a 20 mm strap width, but it does not establish that every 20 mm replacement strap will attach correctly; check the actual attachment and dimensions before buying a replacement.
Water resistance: 3 ATM (30 m)
The published rating is 3 ATM, also given as 30 m. Treat this as a limited water-resistance rating, not as an indication that the watch is suitable for swimming or diving. The specification sheet does not provide a more detailed activity rating.

Christopher Ward lists a timing tolerance of +20/-20 seconds per day. Time+Tide also highlighted that specification in its launch coverage. It is a stated tolerance, not evidence that every individual watch will gain or lose the maximum amount; no independent timing measurements are established here.
