Miyota · Automatic caliber guide
A slim movement. A useful date.
The 9015 fits hours, minutes, central seconds, and a quickset date into a 3.90 mm movement. It offers the same 4 Hz beat rate and approximate 42-hour reserve as the no-date 9039, with a calendar for readers who like that extra piece of everyday information.

My take
I would choose between a 9015 watch and a 9039 watch by asking whether I actually use the date. If I do, the 9015 offers it without an increase in the published movement height. I would then compare the case dimensions, dial readability, and the watch brand’s timekeeping commitment.
Beyond the spec sheet
Wind clockwise with the crown in its normal position. Miyota’s manual says a few turns will start the movement; that is not a full-reserve claim. At the second click, the seconds hand stops so you can set the time. Unlock a screw-down crown first, following the watch’s manual. [source]
Miyota says not to quickset the date between about 8:30 p.m. and 2 a.m., according to the time shown by the watch. The date may fail to change the next day if adjusted during that interval. Move the hands outside it before using the first crown click for date correction. [source]
Two brands can regulate the same base movement differently. Look for the tolerance stated for the exact watch, and keep that separate from Miyota’s movement specification. If a product page and its manual disagree, ask the brand which applies to your reference.

Useful comparisons for choosing a watch. These are not claims of parts compatibility.

Reference A5-FB-FKM20BLK-NY20KHA
The A5 Field Black automatic product page explicitly identifies Miyota 9015. Vaer’s similarly styled C5 is a different, solar-powered watch.
Reference S02-HP26-VI15
The Hamburg Pro Automatik Alabaster specifies Miyota 9015. The Pro designation matters; other Hamburg models have different movements.

Quick answers
The 9015 has a date and a separate quickset position. The 9039 is a true no-date movement. Their published frequency, movement height, approximate reserve, and accuracy range match, but that does not make them interchangeable.
Yes. Turning the crown in its winding position adds energy, and pulling it to the time-setting position stops the seconds hand. The watch brand’s manual explains any screw-down crown.
I would not make that judgment from the names alone. The 9015 has a thinner movement and a similar headline reserve; the SW200-1 comes in different executions. The complete watch’s accuracy commitment, case, warranty, and service options are more useful buying criteria.
