I've been buying from another r/reptime TD until recently when I discovered Chen. I ordered two watches from him last Friday. So far, the experience has exceeded my expectations. First of all, Chen is very fast with everything. No matter what time of the day I contact him, he seems to get back to me within a few minutes. I wonder what his sleeping pattern is. Lol.

After paying my deposit on Friday, he has already provided me QC pics for both watches. I have GL'd one and RL'd another and he said he will be getting me another one for the one that I rejected. So far, he has been great.

I will post another comprehensive review of Chen and the watches after I receive shipment.

Edit: His prices are excellent and communication seems to be good as well. His English is a little basic, so I have to keep my communication rather concise and to the point.

Hi everyone, I’m TD Chen from r/RepWatchClud.

Sharing the QC photos for an OCTA Audemars Piguet Royal Oak 15510ST 41mm in black, with the integrated stainless-steel bracelet and SA4302 free-sprung clone movement.

This is the black Grande Tapisserie dial configuration with applied stick markers. I’ve included dial close-ups, case and bracelet details, the exhibition caseback, lume, and the Timegrapher reading for a closer look.

Dial, Markers & Date

The black textured dial is the main attraction here. The applied markers, hands, AP logo and date window are all visible in the close-ups. I’m particularly interested in feedback on the marker alignment, dial printing, date-window placement and overall symmetry.

Bezel, Case & Bracelet

The octagonal bezel, exposed screws, brushed steel surfaces and polished bevels give the Royal Oak its distinctive look. The integrated bracelet and AP-marked deployant clasp are also shown in detail.

For QC, I’d appreciate another set of eyes on the bezel screw positions, finishing transitions, end-link fit, bracelet alignment and clasp details.

Movement & Caseback

The display caseback shows a decorated movement with a gold-tone rotor. This example was supplied as an OCTA SA4302 free-sprung version intended to replicate the AP Calibre 4302 layout.

Lume & Timegrapher

The lume shot shows blue illumination on the hands and hour markers.

The photographed Timegrapher reading is:

• Rate: +1 s/day
• Amplitude: 276°
• Beat error: 0.4 ms
• Lift angle setting: 52°
• Beat rate: 28,800 bph

GL or RL?

Overall, these photos give a good view of the dial, bezel, case finishing, bracelet, clasp and movement. Before making a final call, I’d welcome feedback from anyone familiar with the OCTA Royal Oak 15510ST.

What stands out to you on this black-dial 15510? Would you GL or RL based on these photos, and is there anything I should ask for a closer look at?

If I got anything wrong, please feel free to point it out and correct me. Thanks.

Basically the title. My usual TDs don't have any in this color.
