RCF vs VSF 126613LB Bluesy — VR3235 vs DD3235 V2 Side-by-Side
Hi everyone, I'm Chen,TD from r/RepWatchClud.
Today I'm sharing a side-by-side comparison of two Rolex Submariner Date 126613LB Bluesy builds.
RCF is on the left, VSF is on the right.
This is the 41mm Two-Tone Yellow Rolesor / Blue Dial / Blue Bezel configuration, commonly called the Bluesy, 126613LB Bluesy, or 41mm Bluesy in the rep community.

Dial & Gold Tone
The first thing to compare is the blue dial and two-tone gold finish.
Both have the same overall Bluesy layout, but you can see differences in how the blue dial reflects the light and how the gold tone appears across the bracelet, bezel and crown.
For QC, I'd focus on:
blue dial color → sunburst effect → dial printing → marker alignment → gold tone → brushing/polishing.
Lighting can change the appearance quite a bit, so these are best judged side by side.
Datewheel & Cyclops
Both samples show 7, which makes this a useful direct comparison.
The datewheel can be checked for:
font shape → thickness → centering → vertical position → date-window alignment → Cyclops magnification.
Bezel
Both use the blue Submariner bezel with gold-filled numerals.
The close-ups allow comparison of:
blue ceramic color → numeral shape → minute markers → pearl/lume pip → bezel alignment.
Case & Crown
Both are 41mm Submariner cases.
The side shots show the case profile, crown guards, Triplock crown and gold/steel finishing.
The supplied thickness is:
RCF: 12.2mm
VSF: 12.3mm
Bracelet & Clasp
Both use the two-tone Oyster bracelet with flip-lock clasp.
The useful QC points are:
SEL fitment → center-link finishing → gold tone → brushing → clasp engraving → bracelet transition.
Lume
Both show blue lume.
The lume shots are useful for checking marker coverage, consistency and bezel pip brightness.
Movement
This is probably the biggest technical difference in the comparison:
RCF — VR3235
VSF — DD3235 V2
Unlike many exterior-only comparisons, these photos actually include the movements.
You can directly compare the rotor engraving, plate layout, finishing and visible movement architecture.
Weight
The actual scales in these photos show:
RCF — 181.48g
VSF — 179.62g
That's only about 1.86g difference between these two samples.
My Side-by-Side Take
For this pair, I'd focus on:
gold tone → blue dial → datewheel/Cyclops → bezel → case finishing → bracelet/SEL → lume → VR3235 vs DD3235 V2 → actual weight.
Both are the same 41mm 126613LB Bluesy, so this is mainly about the differences in factory execution, finishing, weight and movement configuration.
What do you guys notice between the RCF and VSF Bluesy?
If I got anything wrong, please feel free to point it out and correct me. Thanks everyone.
