Detailed review

Measured readings and evidence limits

Two scale readings make this review useful: 132.9 g for the grey-dial Oysterflex-style Daytona and 183.4 g for the black-dial, metal-bracelet Daytona. The reviewer identifies them as VS Factory weighted versions, respectively V2 and V3. The footage supports recording those readings; it does not establish a uniform factory weight, a tungsten composition or a match to genuine white-gold weight.

Key takeaways:
- The configurations correspond visually to 116519LN and 126509. The presenter's Little Le Mans nickname refers here to the black-dial 126509-style watch with a metal tachymeter bezel, not evidence of a special Le Mans calibre or configuration.
- The reviewer describes a weighted case but an unweighted clasp on the Oysterflex-style sample; for the bracelet sample, he describes weighting in the head, bracelet and removed caseback.
- These construction statements remain attributed explanations. No components are weighed separately or tested for material composition.
- The supplied recording identifies DD4130 for the grey sample and shows the opened black-dial sample identified as DD4131. It includes no timed reserve test.

Identify the samples before comparing weight

The older-style grey model has a steel-grey sunburst dial, black subdials, a black ceramic-style tachymeter bezel and a black Oysterflex-style strap. Its layout and the reviewer's older-reference description correspond to 116519LN. The 116519LN description from official Rolex retailer Mamić documents the genuine steel-and-black dial and Oysterflex configuration.

The second watch has a black dial, contrasting silver-tone counters, elongated hour markers, a silver-tone metal bezel and an Oyster-style bracelet with three-piece links. That combination corresponds to 126509. Rolex's 126509 specification identifies the genuine bright-black-and-steel dial, metal tachymeter bezel and Oyster bracelet. Genuine white-gold material specifications do not establish the composition of either replica here.

The supplied subtitle repeatedly says VS Factory, normalised here to VSF. The video's Clean Jacky watermark is branding and does not independently establish manufacturing origin or override that source attribution. Neither factory nor reference engraving is independently authenticated.

What the scale actually shows

Around 01:10–01:12, the grey Oysterflex-style sample is on the scale and the display reads 132.9 g. Around 03:18–03:20, the metal-bracelet sample reads 183.4 g. These are the displayed readings for the presented configurations, not certified net-mass specifications.

Both watches rest on a support fixture. The selected weighing sequence does not document a calibration check or establish the fixture's tare treatment. Protective films are visible, and bracelet sizing and link count are not recorded. For a reproducible comparison, request an empty-scale zero, a visibly tared support if used, and the actual watch with its fitted links and films accounted for.

Before the second reading, the narrator quotes an approximately 185 g factory figure and says deviations may be about one gram. The displayed 183.4 g is 1.6 g below 185 g. That arithmetic should remain visible rather than be rounded into proof of the quoted tolerance. The nominal figure and tolerance are his statements; the reading is the recording's evidence.

The two displayed values differ by 50.5 g, but the watches also differ in case generation, strap or bracelet and attributed movement. There is no unweighted counterpart on the scale. This cannot establish how many grams the weighting upgrade adds or how much of the difference comes from the bracelet.

Weighting locations: explanation versus demonstrated structure

For the grey sample, the reviewer calls the case weighted and explicitly says the clasp is not weighted. A 6LV marking is visible during the clasp inspection. His assurance that the case finish will not peel, supported by an anecdote about another model, is not a durability test of this watch.

For the black-dial sample, he describes weighting in both the head and bracelet. He presents the links while praising the absence of visible seams and says the resulting wrist balance is good. These are construction and wearing assessments, not a sectioned-link inspection or a measured centre-of-mass result. Film and surface marks further limit what the close-ups can establish.

At roughly 05:04–05:12, the removed caseback is shown and described as weighted. It is not weighed separately. The recording does not identify the weighting material through a test or establish a specific insert, alloy, rotor or rehaut construction. In particular, it provides no basis to convert weighted into tungsten-filled or solid precious metal.

Au750 and other hallmarks are visible during the newer sample's inspection. They are markings on a replica, not an assay. Its clasp reads 5NX. The narrator also mentions an elephant sticker as an identifier. Codes and stickers can be recorded for the offered sample, but do not authenticate a factory or a production batch.

Movement and controls: what carries over, what is new

The grey sample is identified in speech as Dandong 4130, or DD4130. During the control sequence, the presenter starts the chronograph, explains stopping before resetting, and demonstrates crown handling. His explanation of the minute counter advancing after one revolution is technical commentary; the short passage is not a full timed one-minute accuracy test. There is no open-caseback DD4130 inspection in this episode.

The newer bracelet sample is opened and identified as DD4131. The reviewer points to the balance-area regulating components and describes their relative thickness. Treat that as his identification method in the shown orientation, not a universal left-versus-right shortcut. His approximately 70-hour reserve claim is untested here. No numerical timing report or long-term reliability study is supplied.

For existing movement background, see DD4130 and DD4131. The earlier VSF versus Clean Daytona comparison concerns different, 126500LN-style samples. Its conclusions should not be transferred automatically to these weighted configurations.

QC questions that follow from this evidence

A RepTime 126509 V3 owner discussion reports a broadly similar complete-watch reading while describing end-link noise; another owner reports no bracelet problem. This supports asking for sample-specific articulation and sound checks, not declaring a universal bracelet defect. A weighted-Daytona construction discussion includes speculative claims about internal tungsten parts. Those comments do not verify this video's samples.

Ask for a repeatable weighing clip, the offered strap size or link count, clasp engagement, end-link fit and a movement view if identification matters. Request a short handling clip to assess unusual bracelet or caseback noise. Examine finish continuity with protective films accounted for. Wrist balance, finish durability and movement performance need their own evidence; a heavier reading does not answer all three.

Sources & provenance

Strengths

Two displayed scale readings, different strap and bracelet configurations, clasp markings and opened DD4131 sample.

What to watch for

Tare and calibration undocumented. No unweighted counterpart, material assay, component weighing or durability test. Version labels and construction claims remain attributed.

Questions answered

Do V2 and V3 identify the same upgrade across both watches?

No. They are the reviewer's labels for two different configurations: grey Oysterflex-style V2 and black-dial bracelet V3. The recording does not establish a universal VSF generation system or a dated production batch.

Does this video prove tungsten weighting or genuine-watch weight?

No. It shows scale readings and a removed caseback, alongside the reviewer's descriptions of weighted components. There is no material test, component-by-component weighing or genuine comparison under matched conditions.

Is 183.4 g the official weight for every VSF 126509 V3?

No. It is the displayed reading for this presented sample. Tare treatment, protective material and bracelet sizing are not fully documented. The reviewer's approximately 185 g figure is not a verified batch specification.
