Rolex Datejust: Reference 79174 Caliber 2235
Symptoms: Regular maintenance
Repair contents: Overhaul, spring and gasket replacement, case and bracelet cleaning
Repair cost: 27,500 yen
I disassembled it and cleaned it. There are no problems due to regular maintenance.
Replace the mainspring and assemble. Since the movements for ladies are small, the work is more detailed, but Rolex's Cal. 2235 has a solid structure and is easy to assemble. There are some models with difficulties with calibers earlier than 2235. I hope to introduce them again soon.
Assemble the dial side as well. The conch-shell-like part you see on the left is what jumps the calendar. By the way, a datejust is a mechanism that jumps the date instantly, and does not mean that it changes to exactly 12 o'clock.
The dial and hands are attached. It appears to be in good condition and has been regularly maintained.
We also assembled the automatic winding unit. The ladies' version is slightly less accurate than the men's version, but we will adjust it so that it meets the chronometer standard. The ladies' chronometer standard is -5 seconds to +8 seconds. In reality, we will adjust it to be a little more accurate, but the tolerance for accuracy will vary depending on the year and condition.
We will continue to provide repair information.
