Waltham Aircraft Clock Corp

Waltham Aircraft Clock Corp, doing business as Prime Time Clocks, manufactures and repairs precision mechanical and electronic aircraft clock components and assemblies for the U.S. Department of Defense as a prime contractor operating under small disadvantaged business (SDB) and woman-owned small business (WOSB) certifications. The company is a self-certified SDB and WOSB headquartered in Ozark, Alabama, competing predominantly in full-and-open procurements without formal set-aside designations on most task orders, though several of its underlying indefinite delivery contracts carry Total Small Business set-aside status.

Prime Time Clocks' federal work centers on aircraft timekeeping components—hand assemblies, staff assemblies, balance wheels, crystals, lamp board assemblies, crowns wheels, gaskets, springs, barrels, and complete clock panel repair services. Representative recent awards include a $25,408.79 Total Small Business purchase order from DLA Land and Maritime for crystals (July 2025), a $21,228.24 delivery order from DLA Aviation for balance and completion services (May 2024), and a $41,145.12 purchase order from Air Force Materiel Command for aircraft panel clocks (November 2022). The company also supplied $10,190 in panel clocks to Naval Supply Systems Command (March 2024) and maintains an active $1,350 delivery order from Naval Supply Systems Command for panel clock repairs extended through December 2022.

Customer concentration is heavily skewed toward DLA Aviation. Of 621 total awards across the portfolio, DLA Aviation accounts for 350 awards (56% of count) and $7.3 million in combined potential value (53% of dollars). DLA Land and Maritime follows with 74 awards and $1.6 million, while Naval Supply Systems Command holds 41 awards for $421 thousand. Air Force Materiel Command represents $2.7 million in potential value across 26 awards—the second-largest dollar concentration—indicating that while DLA Aviation dominates order frequency, AFMC places larger individual orders. Together, these top five agencies account for 84% of awards and 94% of combined potential value, reflecting a highly concentrated customer base.

Prime Time Clocks holds eleven active single-award indefinite delivery contracts with DLA Aviation, DLA Land and Maritime, and Naval Supply Systems Command, each with ceiling values of $250,000 and performance periods extending through 2030. The most recently awarded IDCs include a Total Small Business set-aside contract from DLA Land and Maritime for aircraft clock crystals (October 2025, $250,000 ceiling) and two unrestricted IDCs from DLA Aviation for hand and minute totalizer components and staff assemblies, central (September 2025, each $250,000). Earlier vehicles include a July 2025 Total Small Business IDC from DLA Aviation for hand and minute totalizer components, a September 2024 IDC for hand assemblies (extended through September 2030), and single-award IDCs dating back to February 2022 for crystals procured through DLA Land and Maritime. The company executes task orders under these vehicles on firm fixed-price basis, with individual orders ranging from under $100 to $25,000 or more. Top IDV vehicles by execution include an Air Force IDC (FA811709D0010) with 14 task orders totaling $891 thousand and an Army IDC (W52H0905D0025) with 10 task orders valued at $1 million.

Activity has been sustained over the past five years, with 35 awards in 2022, growing to 52 in 2023 before stabilizing at 43–46 annually in 2024 and 2025. The 2026 count reflects only partial-year data (7 awards through April). Combined potential value across all 621 awards totals $13.9 million, with $11.3 million (81%) already obligated, indicating consistent cash flow and execution. The company's award portfolio spans 621 prime contracts and IDVs with no subcontract work reflected in the source—Prime Time Clocks operates exclusively as a prime contractor to defense agencies.

Product concentration aligns with timekeeping manufacturing: 455 awards fall under Time Measuring Instruments PSC; 46 under Oscillators and Piezoelectric Crystals; and 261 awards under NAICS 339517 (Other Measuring and Controlling Device Manufacturing). Secondary NAICS codes include 334419 (Other Electronic Component Manufacturing) at 86 awards and 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) at 64 awards, reflecting the precision mechanical and electronic nature of the work and the aviation platform context.
