Two chronographs can share the same movement and proportions while giving you a very different first impression. That’s the choice between our Snoopy and Moonwatch-style Seiko mods: a blue-and-white dial with a lighter feel, or the familiar contrast of a black dial and white markings.
Both are independent custom watches hand-assembled by Somerville Watch Co. The useful comparison is how the designs fit your taste and the way you wear a watch.
Start with the two dial designs
The Seiko Mod Speedmaster – Snoopy Chronograph is the blue-and-white option. Blue subdials, hands, and bezel details bring color to the watch without changing the basic chronograph layout.
The Seiko Mod Speedmaster – Moonwatch Chronograph takes the black-dial direction. Light-colored hands and markings stand out against the darker background, giving the whole watch a more restrained appearance.
Look at the dial and bezel together. Their combined contrast is a bigger part of the watch’s character than any one detail in a close-up.
Choose Snoopy for a lighter color palette
The white background makes the blue accents an easy focal point. If you often wear denim, blue shirts, or lighter neutrals, this is a natural place to start.
You can also choose it simply because the color makes you smile. A watch is something you’ll look at many times a day, and enjoying the dial is a perfectly good reason to prefer one version.
Choose Moonwatch for classic black-and-white contrast
The black version keeps the palette simple. It’s worth considering if you like a watch to work with several outfits and prefer most of its personality to come from the shape and subdial layout.
Compare the hands with the dial background, then look at the small markings. The version that feels clearest and most balanced to you is usually a better choice than whichever nickname you noticed first.
The same VK63 meca-quartz foundation
Both current listings specify a VK63 meca-quartz chronograph movement. It uses battery-powered quartz timekeeping with mechanical chronograph action, so neither watch needs winding as part of your daily routine.
The upper pusher starts and stops the timer; the lower pusher resets it. Running seconds appear on a subdial, while the large central chronograph hand is used for timing sessions. The 24-hour subdial follows the main time display.
One detail to understand on the current Moonwatch dial: its minute-counter scale is marked to 30, while the VK63 measures elapsed time up to 60 minutes. The product listing explains that dial detail, and the manufacturer’s VK63 manual explains the movement’s displays and controls.
Compare the fit, not just the colors
Both current versions list a 40 mm case, 12 mm thickness, 47 mm lug-to-lug length, and 20 mm lug width. Each lists a weight of 134 g and a stainless steel bracelet.
That means this particular choice is mainly about the visual direction. The sapphire crystal, aluminum bezel, and shared dimensions give you a consistent starting point for comparing the two.
Which one would you reach for?
Choose the Snoopy if the blue details and light dial are what keep drawing you back. Choose the Moonwatch if you prefer the darker dial and simpler color palette. Then check the current product photographs and selected options before making the final call.
Both include our 1-year in-house warranty. Explore the Speedmaster-Inspired Seiko Mods, or get in touch if you’d like help comparing the two.
