: WRIST ICONS presents the IWC 3509 Ocean Bund Waffentaucher Full
: Set. This is one of the most iconic military diving watches ever
: made. These military IWC Bundeswehr watches don’t pop up that
: often. And especially not with this so iconic dial configuration
: with the 3H circle on it. And a full kit, with box, toll, manual
: and papers.

: History of the IWC Ocean Bund

: The IWC Porsche Design Ocean Bund a very collectable military
: watch. It follows IWC’s grand tradition of military watches
: and, in fact, was the last production model that IWC made
: specifically for actual military use. It is a very rare watch in
: all its variations and, in the even rarer minesweeper variation,
: it follows IWC’s antimagnetic watch tradition. Of course, it
: also is a Porsche Design model with its purity of design. Above
: all else, it is a diving watch.

: In 1980 the German Navy placed an order at IWC to develop a new
: Divers Watch. In a 30 pages brochure, the Navy determined which
: specifications they demanded. The most important specification
: was, along with sturdiness, extreme degree of waterproof etc.
: that some of the new watches should be completely anti-magnetic.

: After the successful launch of the Porsche Design line of watches
: in 1978, perhaps as an attempt to survive in face of the quartz
: onslaught, IWC introduced a Porsche-styled titanium diving
: watch, the Ocean 2000. It also obtained a contract with the
: then-West German military, the Bundeswehr, to make a variation
: of that watch for their Navy.

: Alexander Porsche, had created the famous civil Ocean 2000, a watch
: made from mainly titanium, a non-ferro metal. IWC guaranteed
: that this watch was water proof until 2000 meters!. It seemed
: logical that the military version should be a super development
: of the civil Ocean 200 which already had a lot of titanium in
: its construction, rather than a further development of the
: already existing IWC "Aquatimer",ref. 1812, which was
: a steel watch.

: Juergen King, technical director of IWC in 1980 was assigned to
: lead the project. During a time span of 4 years: 6 different
: military Bunds were developed.

: These are:

: Ref. 3314 Quartz, 3H dial

: Ref. 3319 Quartz, 3H dial

: Ref. 3509 Mechanical,"plain" dial

: Ref. 3509 Mechanical, 3H dial

: Ref. 3529 Mechanical, "plain" dial

: Ref. 3519 Mechanical, 3H dial

: From these Bunds ,ref. 3519 AMAG(anti-magnetic) is the most special
: and rare. Although, neither IWC nor the German Navy will reveal
: the total production, it is a well kept secret that there are no
: more than than 50 Bunds ref. 3519 AMAG around, world wide. It is
: the first and only completely anti-magnetic divers watch in the
: world.

: The Porsche Design Ocean watch for the Bundeswehr had various minor
: design changes from the civilian version. These primarily
: involved a black bezel, an orange minutes hand, a flat sapphire
: crystal, and a nylon strap (a titanium bracelet was sold to the
: German Navy separately and was not affixed by IWC to the watch).
: In addition, to comply with the Bundeswehr's specifications, the
: watch was tested for water resistance to "only" 300
: meters, unlike the 2000 meters of the civilian Ocean 2000.
: However, one German military watch expert told me that the
: watches were more water resistant than 300 meters, but only
: tested to the that standard. Source mrwforum

: Distribution of the IWC Ocean BUND

: None of the watches was transferred directly to the german
: military. The IWC contract was with Diehl Avionik Systeme,
: Frankfurt; the watches were delivered to them for transfer to
: the bund. DAS was already a qualified military supply source AND
: had a corporate relationship with VDO (a manufacturer of
: original replacement parts such as electronics and mechatronics,
: who owned IWC during the period when the ocean bund watches were
: made). the watches were delivered over approximately a 12-15
: year period from the early 80s to the mid 90s. further, some of
: the case references had sub references. the 3509, e.g., existed
: in 3509-001, -002, and (possibly) -003 form. that case reference
: was issued to combat divers (kampfschwimmer), fire/SAR divers
: (tauchdienst), and clearance divers (taucher). different dials
: were issued (plain and 3H) and different NSNs were assigned to
: each sub-reference. the same may have been true of the other
: case references; i have concentrated on the 3509. replacement
: parts, including dials, hands, and bezels were also supplied,
: and it is unknown to what extent the distinctions among the
: dials were kept straight during service. Source mrwforum

: Design of the Taucheruhr oder Waffentaucher

: Wristwatch for divers, IWC Reference nos. 3509 or 3529 introduced
: 1983 (ref. 3509) and 1984 (ref. 3529). Bundeswehr planning
: number 6645-0103; BUND stock nos. 6645-12-197-9681 or
: 6645-12-197-8096 (Ref. 3509) and 6645-12-339-1536 (Ref. 3529)

: This version used an automatic movement that beat at 28,800
: half-beats per hour. The first ones used IWC cal. 375, which
: represented IWC's first use of an ETA 2892 base movement. Later
: ones used an enhanced version of that movement, the IWC cal.
: 37521. As mentioned below, these movements had 22 rather than
: the more standard 21 jewels found in the 2892. The
: "extra" jewel was actually six jewels that served the
: same function, and replaced steel rotor bearings.

: The Bundeswehr specifications appear to require the same rate
: standard of these models to the civilian Ocean 2000, which was 0
: to +8 seconds per day. The movement was required to have more
: than 40 hours power reserve.

: While apparently not as luminous as the quartz model, the
: specifications for this watch required "long glowing
: material on dial, hands and at the bezel, type DIN 67510".

: Again, like the other models, this version was water resistant to
: 300 meters and was supplied with a Nylon-Velcro strap. Like the
: quartz Kampftaucheruhr the two reference numbers differentiate
: the design of the strap attachments. The watch weighed 43 grams.

: Condition

: This stunning example of this IWC 3509 Ocean Bund Waffentaucher
: vintage condition. It has all the good parts what makes this a
: great looking vintage piece. The watch is worn regularly and the
: case is unpolished.

: Dial: This IWC Ocean Bund features a rare 3H dial. A red circle
: with the inscription 3H in the upper right corner of the dial
: indicates the tritium luminescent used in the dial and in the
: bezel. It comes with an additional dial. The three-liner
: "IWC, International Watch Co., Schaffhausen" is offset
: to the left. During army combat these tool watches had to be in
: immaculate condition since they were life saving devices.
: Therefore the swapped parts to keep the performance like new.
: The matte black dial has original lume that has aged to a
: beautiful yellowish vintage color.

: Hands: Original "BUND" Tritium hands. The patina of the
: snowflake hands match the patina of the hour markers. Most
: likely the hands have been changed during service since this was
: . The lume of hour hand of early Tudor Snowflake are notoriously
: prone to get a break in the lume or loose a part of the
: luminescent material.

: Crystal: The Ocean Bund has a flat sapphire crystal.

: Case: Case shows wear. (Please see pictures). The titanium bezel is
: rotatable in one direction, as is common in professional diving
: watches.

: Crown: Original IWC crown.

: Bezel & Insert: Original blue bezel with stunning original fat
: font faded blue insert.

: Bracelet: IWC signed titanium bracelet with correct links. Comes
: also with the NATO strap. Like other titanium watches produced
: by IWC in the 1980s, the connection design for the bracelets
: evolved. As mentioned above, slightly different fastening
: systems were used and there were different reference numbers for
: each variation. However, usually the watches were ordered only
: with a Nylon-Velcro-strap. The titanium-bracelets were ordered
: separately and were not mounted by IWC to the watches. The nylon
: straps had the separate BUND stock no. 6645-12-197-8310. The
: older style titanium bracelet had BUND stock no.
: 6645-12-197-8310 and its successor was BUND stock no.
: 6645-12-339-2164. The older bracelets used two silver pins while
: the newer ones used a tube with one steel pin. All IWC Ocean
: Bund watches had the planning number on the case back and either
: the back of the Nylon-Velcro strap-connection part or the first
: link of the bracelet. However, a few watches of the
: Bundeswehr-type were sold to VDO executives and do not have the
: planning number.

: Movement: Just serviced by our watchmaker. Running perfectly with a
: one year service warranty. The watch carries the self-winding
: IWC caliber 37521 based on ETA calibre 2892 with a date disc,
: polished decorations and circular Côtes de Genève finishings.
: The movement features 22 jewels and a bi-directional central
: rotor, beating at 28,800 A/h, with a power reserve of 42-hours.
: The movement is clean, and during the time of testing the watch
: was fully functional.

: Accessories: The full set of this Ocean Bund significantly
: increases its collector's value. The watch comes with its
: original square white box, titanium bracelet, nylon velcro
: strap, screwdriver, instruction manual, hangtag. The engraved
: numbers on the titanium band, velcro band and on the screwdriver
: are all correct.

: Notes: Absolutely stunning example of a super desirable IWC 3509
: Ocean Bund Waffentaucher with an attractive dial and original
: hands. Very hard to find these in this condition.

: Overall, the IWC 3509 Ocean Bund Waffentaucher is noteworthy, both
: for its design and execution. This IWC 3509 Ocean Bund
: Waffentaucher is remarkably well preserved.

: As with all of our pre-owned watches this watch comes with a full
: 12 month warranty with ourselves that will be invoked from the
: day of purchase.

: Viewings can be arranged at our office by appointment.
