A smaller front does not mean every number shrinks

GRANDMASTER-NINE's official page lists 54 / 20 / 145 mm, a 146 mm frame width and 50.1 mm frame height. GRANDMASTER-EIGHT lists 54 / 18 / 140 mm, a 148 mm frame width and 51 mm height. The NINE is therefore 2 mm narrower across the published front and 0.9 mm shorter in published height.

At the same time, NINE's bridge figure is 2 mm larger and its temples are 5 mm longer. Both have 54 mm lenses, while lens height changes from EIGHT's 41.8 mm to NINE's 41.2 mm. This comparison explains the apparent contradiction: front compactness, bridge spacing and temple length describe different parts of the object.

What the catalogue images show

KUANGTU's DTS 464 record uses reference images labeled GRANDMASTER-NINE. The black front has broad rims, softened rectangular lens openings and a shallow dip above the bridge. Two small bright details appear at each outer corner. The side image shows a long metal-colored plate where the temple meets the front.

DITA's official description names an oversized titanium three-barrel hinge plate with enamel inlay. That description provides context for the visible connection area, but the catalogue image does not verify the metal or internal hinge construction of the goods being quoted. The pale transparent reference in the same gallery also changes how much of the connection is visible through the front.

How to use the comparison when replacing a frame

If a customer finds EIGHT too wide at the outer front, NINE's smaller published width makes it a reasonable candidate to examine. It does not establish that NINE will sit closer at the nose, because its stated bridge is wider and bridge contact depends on shape as well as the number.

For a meaningful sample comparison, request front width, temple spread and side photographs at the same scale. Note where the bridge actually contacts the nose and how the temple bends align with the ears. These are assessment steps, not results of a wear test; KUANGTU has not physically tested the two official frames for this article.

Keep the DTS 464 supply record separate

The supplier record archive-2372-dts-464 lists 54 / 20 / 145 mm, matching the three main official NINE values. It does not provide a separately measured 146 mm front width or 50.1 mm height. Agreement on the size triplet is a useful consistency check, not confirmation of materials, origin, lens performance or provenance.

Quote the exact SKU and desired color in the existing enquiry tools, together with quantity and destination. Ask for current photographs of the offered item and its complete markings before using the official comparison as a substitution decision. Keep packaging and commercial terms tied to that same confirmed reference.
