Top pick: a 35 mm stainless steel 7118/1A-style build with a blue sunburst dial, a serviceable automatic movement with center seconds, and a bracelet whose brushed and polished links match the case finishing. That pairing covers what buyers notice first, which is how the blue reads in daylight, and what they notice second, which is how the bracelet sits on the wrist. I judged the field on four criteria: case profile and thickness, dial color and texture accuracy, movement type and serviceability, and bracelet articulation and clasp quality.
What the 7118 Blue Dial Reference Actually Is
Patek Philippe lists the 7118/1A as a steel Nautilus self-winding reference in the 35 mm range with a blue dial and applied numerals. The genuine piece is slim, so a replica that runs two millimeters thicker feels bulky the moment you hold it. The dial is the hard part to copy. A real blue Nautilus dial shifts from deep navy in shade to a lighter mid-blue in direct sun, and the texture under the hands has depth rather than flat paint.
Every watch described here is a replica. It is not a Patek Philippe, it carries no manufacturer warranty, and it holds no collector value. Compare any replica against the current published specifications on the maker's own site before you spend money.
Entry Tier Builds
These are the sub-entry and entry-level automatic builds that show up at low price points.
- Pro: Cheap enough to treat as a test piece if you are unsure about the 35 mm size on your wrist.
- Pro: Simple movements are easy to swap if one stops.
- Con: Dial blue is often flat and slightly purple in shade.
- Con: Case edges feel sharp, and the bracelet pulls hair.
- Con: Gaskets are unreliable, so keep it away from water.
Buy this if you want to check the size and shape before committing to a better build, or you need a watch for travel where loss is a real risk.
Mid Tier Builds
This is where the blue dial starts to look correct and the case profile gets close to the original proportions. Movement options in this band include the Miyota 9015 and the Seiko NH35, both of which have published specifications and spare parts.
- Pro: Dial color holds up in sunlight instead of going flat.
- Pro: Movement is documented, so any watchmaker can regulate or service it.
- Pro: Bracelet screws are usually the correct type rather than pin-and-collar shortcuts.
- Con: Bezel brushing can be a touch coarse next to the polished bevel.
- Con: Date wheel font is the most common tell at this tier.
Buy this if you want the best balance of dial accuracy and day-to-day reliability, and you plan to wear it often rather than store it.
Top Tier Builds
These use Swiss or Swiss-assembled automatics such as the Sellita SW300 family or an ETA 2892 derivative, plus stamped dial texture and hand-finished case bevels.
- Pro: Dial texture catches light the way the reference does.
- Pro: Case thickness is closest to the original, so it slides under a cuff.
- Pro: Crown action and date change feel crisp.
- Con: Costs several times a mid tier build for gains most people will not see at arm's length.
- Con: Parts for the movement cost more to replace.
Buy this if the blue dial and the slim profile are the whole point for you, and you want a watch that survives a decade of regular wear.
Checks Before You Pay
- Ask for a photo of the dial in shade and in direct sun, not a studio shot.
- Ask for the measured case thickness with calipers, not the listed number.
- Confirm which movement is inside and whether parts are available.
- Check that the bracelet tapers and that spare links are included.
- Confirm the return window in writing before shipping.
Legal and Practical Notes
Counterfeit branded goods are subject to seizure at the border in the United States, so an order can be stopped before it reaches you. Selling a replica as a genuine watch is a separate and more serious problem than owning one. Treat any replica as a fashion item with no resale market, and never present it as the real thing.
