Name: Patek Philippe Calatrava 6007A 6007A-001
Brand: Patek Philippe
SKU: 6007A-001

The 6007A-001 is a steel Calatrava with an olive green dial, produced only from 2020 to 2022 before Patek discontinued it. Short production runs in steel with an off-axis dial color reliably become collector targets, and this one checked both boxes. Prices cleared retail before it even left the market.

What it is

Patek introduced the 6007A in 2020 as a 40mm steel Calatrava powered by the in-house caliber 324 S C, a self-winding movement with a peripheral rotor and a Gyromax balance. The sole reference, 6007A-001, wore an olive green sunburst dial with applied hour markers and a leaf-style seconds hand. Patek discontinued the line in 2022, giving it a production window of roughly two years.

No other dial variants or case metals were released under this reference number.

Buying notes

Verify the dial color carefully in person or under daylight photos: the olive reads quite differently under warm indoor light and some sellers misrepresent it as grey or khaki. Check the case for polishing, particularly the lugs, as owners who serviced through non-Patek channels occasionally had the brushed flanks polished away. Confirm the box and papers are date-matched to the purchase year, since grey-market pieces sometimes arrive with incomplete documentation.

The crown and stem are slender on this case size; inspect for any play or resistance before buying.

Market read

The 6007A-001 was selling at or above its roughly $28,000 USD retail price while still in production. Post-discontinuation, secondary market prices have settled in the $34,000 to $42,000 USD range for clean, full-set examples, with the highest prices going to unworn pieces with original stickers. The steel-plus-unusual-dial combination draws both Patek collectors and buyers priced out of the Aquanaut or Nautilus market, keeping demand steady.

Service expectations

The caliber 324 S C carries a manufacturer-recommended service interval of around 5 to 7 years, consistent with Patek's self-winding movements of this generation. A full service at a Patek Philippe service center typically runs $1,200 to $1,800 USD depending on parts condition. Using an independent watchmaker is possible but may affect future Patek service records.

Authentication

The stainless steel Calatrava is rarer than gold variants; verify the 18k hallmark claim versus the actual steel case and check for the Clous de Paris caseback.

Known issues in the market

Some listings incorrectly claim white gold rather than stainless steel; the 18k hallmark inside the caseback is absent for steel.
The Clous de Paris hobnail pattern is on the caseback only for this reference; verify it is present.

Authentication guide

Last reviewed June 2026

The 6007A is the most accessible-priced current Calatrava -- a steel-cased time-only reference with a classical ivory dial and Cal. 30-255 PS manual-wind. As an entry point to Patek, it is a reference where careful applied text and movement finishing verification matters.

Known reproduction risks

LOW

Replica steel Calatrava dress watches in the general Calatrava form factor; the 6007A is a lower-premium target than sport references.

Flat "Patek Philippe" text rather than applied raised text
Hands that appear black rather than blued steel
Caseback without the Calatrava cross in relief, or with a pressed-on cross rather than cast
Applied baton indices at inconsistent angles or heights

Dial

Original: Ivory lacquer. The warmth of the ivory tone is specific -- not pure white, not yellow. Applied "Patek Philippe" text casts a visible shadow. Applied baton indices have a flat polished top surface.

Replacement tells

Pure white dial without the correct ivory warmth -- service dials sometimes differ in tone
Flat "Patek Philippe" text without shadow
Applied indices that appear at inconsistent heights above the dial surface

Hands

Original: Blued steel leaf hands. The blue is thermally achieved and shows gradation toward the tips. Leaf taper is graceful from stem to tip.

Replacement tells

Black or dark grey hands rather than true blued steel
Uniform synthetic coating without the correct thermal gradation
Blunt or thickened hand tips rather than the graceful leaf taper

Case back markings

2019 to present

Solid Calatrava cross caseback in steel with "Patek Philippe & Co Geneve" engraved in a circular arc
Reference 6007A-001 and serial number on the case flank
Stainless steel case -- no precious metal hallmark
Movement visible only at service; Cal. 30-255 PS must be confirmed by a watchmaker

Movement tells

toggle

Cal. 30-255 PS is a manual-wind movement at 2.53mm height. It is one of the thinnest Patek production calibers and produces a notably flat case profile.
Manual wind should feel smooth with progressive spring-back resistance as the mainspring approaches full wind. Any grit, skip, or inconsistent feedback indicates a service requirement.
No date, no quickset, no additional complications. If the watch includes any additional function, it is a different reference.
Gyromax balance wheel with four gold weights and Geneva Seal finishing on all bridges are the authentication standards.
Patek's solid casebacks seal the movement; opening a 6007A requires appropriate tools and a trained watchmaker. Avoid any watch where the caseback shows forced-opening marks or scratches around the case rim.
